A pattern making ruler set helps you draft smooth armholes, necklines, hips, and straight seams with more control than a single ruler can offer. My best overall pick is the HLZC 15-piece French curve set for its broad selection of shapes, while the Cutex four-piece kit suits designers who want a focused set with an L-square. The main tradeoff is between a larger assortment of curves and a compact kit that is easier to store and quicker to sort through. Measurement units matter just as much: metric and imperial sets fit different pattern instructions and work habits. Read on for the full comparison, selection criteria, and guidance on choosing a set for your drafting needs.

Key Takeaways
- The HLZC 15-piece set takes the broadest-coverage role because a larger assortment can handle more curve-drafting tasks, though it may take longer to sort and store than a four-piece kit.
- Cutex is the focused pick for structured drafting: its four-piece kit includes an L-square, a useful distinction from curve-heavy sets that prioritize shape variety.
- LINXIAO, LJLJ, and the unnamed nine-piece metric kit share a practical middle ground of multiple tools in metric units, so compare their listed shapes and included pieces before choosing among them.
- The six-piece HLZC imperial set serves inch-based workflows; it avoids the conversion step that can introduce errors when instructions and tools use different units.
- Compact four-piece options such as Xuhal and Cutex make portability a priority, while 13- and 15-piece sets favor coverage for sewists who draft a wider range of garment shapes.

More Details on Our Top Picks
7-Piece Sewing Ruler Set for Pattern Making
This option stands out for its balance of shape variety and everyday durability, which is why it earns the top slot. Seven transparent acrylic rulers cover the core drafting shapes most garment work demands, and the bend-without-breaking acrylic means a dropped or flexed ruler survives incidents that would crack stiffer drafting tools. Unlike the LINXIAO 9-Piece set, which locks you into metric-only markings, this set includes both metric and imperial scales, so it fits pattern blocks drafted in either system — a real advantage if you work from vintage American patterns alongside European indie drafts. The tradeoff is transparency of information rather than of plastic: the seller doesn’t publish individual ruler dimensions, so you can’t confirm you’re getting a long straightedge before it arrives. Compared with the HLZC 15-piece kit, you get fewer accessories, but what you get is focused and coherent.
Pros:- Seven distinct ruler shapes cover most pattern drafting tasks
- Acrylic flexes without cracking or leaving marks
- Dual metric and imperial scales on the same set
- Transparent bodies make it easy to align over existing pattern lines
Cons:- Individual ruler dimensions are not listed, making it hard to verify a long straightedge is included
- Durability claims in the product description are vague and unverified
Best for: Home sewists and pattern drafters who want a dependable core set of curve and straight rulers in both measurement systems
Not ideal for: Anyone who needs a fully specified kit with accessories like tracing wheels and tape measures — this is rulers only, with unpublished dimensions
- Material:Transparent acrylic
- Set size:7 rulers
- Measurement units:Metric and imperial
- Flexibility:Bends without breaking or marking
- Use cases:Sewing, tailoring, pattern drafting, fashion design
- Accessories included:None — rulers only
Our verdict“The most sensible default purchase for a sewist who wants one durable, dual-unit set that handles most drafting jobs without extra clutter.”
LINXIAO 9-Piece Metric Sewing Ruler Set with French Curves
For pure cost-per-tool value, this LINXIAO set is hard to beat in this lineup. Nine pieces — a mix of straight rules, French curves, and curve templates — give a beginner or occasional quilter everything needed to start drafting, at a piece count that rivals the LJLJ 9-piece set while promising sturdier, more clearly documented construction. The flexible PVC is genuinely lightweight for tossing into a class bag, and the markings stay legible after repeated handling. The honest tradeoff: this is a metric-only set. If your patterns come from American publishers measured in inches, you’ll be converting constantly, which slows drafting and invites errors. It also lacks the tracing wheels and tape measure bundled with the EXTCCT 13-piece kit, so it’s a ruler set in the strict sense rather than a full drafting toolkit. For metric-native sewists, though, none of that matters much.
Pros:- Nine pieces covering both straight and curved drafting needs
- Clear metric markings support precise measuring
- Lightweight flexible PVC is easy to carry and store
- Good piece-to-price ratio for beginners building a starter kit
Cons:- No imperial markings, limiting use with US-pattern measurements
- PVC is softer than acrylic and may not hold up to heavy rotary-cutting pressure
Best for: Budget-conscious beginners and quilters who draft in metric and want maximum tool variety per dollar
Not ideal for: Sewists working from inch-based American patterns — the metric-only markings force constant conversion
- Brand:LINXIAO
- Number of pieces:9
- Material:Flexible PVC
- Measurement system:Metric only
- Model:LX-9CZF
- Included tool types:Straight rulers, curve rulers, French curves
- UPC:783970205513
Our verdict“A smart buy for metric-drafting beginners who want variety without paying for accessories they don’t need.”
HLZC French Curve Ruler Set, 15-Piece Clear Sewing Rulers for Pattern Making
Where other sets stop at rulers, this HLZC kit behaves like a pattern-making starter workshop in one box: ten transparent rulers, a tape measure, a flexible curve ruler, two tracing wheels, and even tailor scissors. That breadth is what separates it from the 7-Piece Sewing Ruler Set, which covers shapes well but assumes you already own marking and measuring tools. The 18-inch straight ruler and 20-inch curve ruler are the pieces I’d highlight — most cheap kits top out shorter, forcing you to join lines when drafting long seams. The compromises are real, though. Mixing inches and metric across different pieces means you’ll toggle between systems depending on which tool is in hand, and the flexible plastic won’t match the rigidity of dedicated drafting squares when you need a dead-straight reference edge. For a first serious kit, the value trade is worth it; for a specialist, it isn’t.
Pros:- 15 pieces cover measuring, drafting, marking, and cutting in one kit
- Long 18-inch straightedge and 20-inch curve ruler handle full garment lines
- Clear plastic keeps fabric and pattern lines visible underneath
- Flexible construction tolerates rough handling and classroom use
Cons:- Mixed inch and metric pieces require mental switching mid-project
- Flexible plastic is less rigid than solid drafting rulers for precision straightedges
- Bundled scissors and wheels are starter-grade, not professional quality
Best for: New sewists or fashion students building a first toolkit who want rulers, marking tools, and scissors in a single purchase
Not ideal for: Experienced drafters who already own quality tracing wheels and shears — the bundled tools dilute spend on the rulers themselves
- Brand:HLZC
- Piece count:15
- Set includes:10 transparent rulers, tape measure, flexible curve ruler, 2 tracing wheels, tailor scissors
- Material:Clear flexible plastic
- Measurement units:Inches and metric (varies by piece)
- Notable ruler sizes:18-inch ruler, 20-inch curve ruler
- Recommended use:Pattern making, sewing, tailoring, design
Our verdict“The right choice when you’re starting from zero and want every pattern-making tool in the drawer on day one.”
EXTCCT French Curve Ruler Set, 13-Piece Sewing Pattern Making Fashion Rulers
This is the set that takes pattern drafting seriously. Beyond standard French curves, the EXTCCT kit includes specialized tools most competitors skip: a hip curve, a grading ruler, a triangle scale, and an arm sleeve ruler. Those shapes matter if you’re grading between sizes or refining armscyes — tasks where the LINXIAO 9-piece set leaves you improvising with the wrong curve. The sharp, wear-resistant scale lines are a genuine differentiator too, since cheaper PVC sets tend to have markings that blur with use; these hold up through repeated drafting sessions. Add two tracing wheels and a tape measure and you have a near-complete workflow. The main drawback mirrors LINXIAO: it’s metric-focused, so inch-first sewists will fight the scale. It also lacks the long 18-inch straightedge found in the HLZC 15-piece kit, which matters for laying out full-length garment lines.
Pros:- Specialized shapes (hip curve, grading ruler, sleeve ruler) go beyond basic French curves
- Wear-resistant metric scale lines stay legible over repeated use
- Bends up to 90 degrees without cracking
- Tracing wheels and tape measure round out the drafting workflow
Cons:- Metric scale is a poor fit for inch-based drafting workflows
- No long straightedge for full garment-length lines
Best for: Intermediate to advanced pattern makers and fashion design students who grade sizes and need specialized curves
Not ideal for: Hobbyists who mainly trace and alter commercial patterns — the specialized grading tools will sit unused
- Brand:EXTCCT
- Number of items:13
- Includes:10 clear sewing rulers, 2 tracing wheels, 1 tape measure
- Specialized rulers:Hip curve, grading ruler, triangle scale, arm sleeve ruler
- Material:Transparent flexible plastic
- Measurement system:Metric
- Flexibility:Bends up to 90 degrees without breaking
- Model:T001-US-FBA
Our verdict“The most drafting-focused set here — pick it when grading and armscye work justify specialized curves over general-purpose shapes.”
LJLJ Clear Metric Sewing Ruler Set, 9 Pieces
If your drafting mostly involves drawing and cutting smooth curved lines — necklines, armholes, hip shaping — this LJLJ set keeps things lean. Nine clear pieces with pink scale markings give it a visual clarity advantage over all-clear-marked rivals like the LINXIAO 9-piece set: the pink lines pop against light fabric and pale pattern paper, which reduces misreads when you’re tracing at speed. The set spans sewing, quilting, and fashion design tasks without the accessory bloat of the EXTCCT 13-piece kit, making it a sensible pick if you already own wheels and tapes and just need curve templates. The honest downsides: the listing doesn’t disclose the material or individual dimensions, so you’re trusting the pink scales and shapes alone when ordering, and like LINXIAO it’s metric-only. It’s a niche pick that earns its place on curve clarity, not on completeness.
Pros:- Nine varied shapes focused on curve drawing and cutting
- Pink scale markings are easier to read on light fabrics than all-clear lines
- Compact set without unwanted accessories
- Suits quilting and fashion design alongside garment sewing
Cons:- Material and ruler dimensions are not specified by the seller
- Metric-only markings exclude inch-based workflows
Best for: Quilters and garment sewists who already own basic tools and want high-visibility curve templates for detailed curved lines
Not ideal for: Buyers who want full product transparency — unspecified material and dimensions make this a gamble for careful shoppers
- Brand:LJLJ
- Set size:9 pieces
- Measurement system:Metric only
- Color:Clear with pink scales
- Material:Not specified
- Use cases:Sewing, quilting, pattern drafting, fashion design, curve drawing
- Part number:frc-009
Our verdict“A focused curve-template set for sewists who value readable pink markings over a fully documented kit.”
Xuhal Fashion Sewing Ruler Set with French Curves, 4 Pieces
This Xuhal set stands out for its aluminum construction on three of the four rulers — a real step up in rigidity and longevity compared with all-plastic sets like the HLZC 6-Piece Imperial Set. The 24-inch hip curve and 24 x 14-inch L-square hold their edge over time, which matters if you draft patterns daily rather than occasionally. The tradeoff is the grading ruler, which is plastic, so the set isn’t uniformly sturdy, and there’s no storage case to keep the pieces organized. Compared with the Copkim 9-piece kit, you get fewer specialty tools here, but the metal build makes this pick better suited to anyone who values long-term durability over sheer piece count.
Pros:- Three of four rulers are sturdy aluminum that resists bending and deformation
- Covers the core pattern-making shapes: curve, hip curve, L-square, and grading ruler
- Clear markings support precise drafting and body measurements
- Works for both beginners and experienced designers
Cons:- The grading ruler is plastic while the rest are aluminum
- No storage case to protect or organize the pieces
Best for: Sewists and pattern drafters who want rigid, long-lasting aluminum rulers for frequent tailoring and quilting work
Not ideal for: Buyers who want a fully matching set — the plastic grading ruler breaks the material consistency
- Pieces:4
- Materials:Aluminum and plastic
- Included Rulers:12-inch curve ruler, 24-inch hip curve ruler, 24 x 14-inch L-square curve ruler, 24-inch grading ruler
- Applications:Clothing design, tailoring, quilting, body measurements, drawing
- Markings:Clear printed measurements
- Storage:No case included
Our verdict“A durable four-ruler core set for drafters who prioritize rigid aluminum tools over a large piece count.”
Cutex Fashion Designer’s Ruler Kit – 4-Piece French Curve and L-Square Set
Where the Xuhal set takes a general-purpose approach, the Cutex kit is built around garment-specific curve work. The Vary Form curves in two sizes are the draw here — they’re shaped specifically for armholes, necklines, sleeve caps, and collars, tasks a generic French curve handles less cleanly. The 24-inch curve stick rounds it out for lapels, elbows, and trouser lines. The main drawback is that there’s no storage case, and the product listing contains typos that hint at loose quality control on the packaging side — the rulers themselves are functional, but it’s worth knowing before ordering. If you’re choosing between this and the Clear Metric 9-Piece Set, this is the better pick for tailored garment details; the 9-piece set wins on raw versatility.
Pros:- Two Vary Form curves sized for armholes, necklines, sleeve caps, and collars
- 24-inch curve stick handles lapels, elbows, and trouser contours
- Complete four-piece coverage of most garment-drafting curve needs
- Clear printed measurement scales on every ruler
Cons:- No storage case included
- Typos in the product description suggest limited quality control
Best for: Fashion students and garment-focused tailors who draft armholes, necklines, and sleeve caps regularly
Not ideal for: Quilters or general crafters who need broad versatility rather than garment-specific curve shapes
- Pieces:4
- Includes:24″ Curve Stick, 12″ Vary Form Curve, 24″ Vary Form Curve, 14″ x 24″ L-Square
- Intended Use:Fashion design, tailoring, pattern making, DIY clothing projects
- Measurement Scale:Printed on rulers
- Storage:No case mentioned
Our verdict“A purpose-built four-piece kit for garment drafters who need true fashion-design curve shapes rather than generic rulers.”
Clear Metric Sewing Ruler Set, 9-Piece French Curve Pattern Ruler Kit
This 9-piece set makes the most sense for new pattern makers who don’t yet know which shapes they’ll reach for most. With straight, L-shaped, and French curve rulers plus flexible, bendable bodies, it lets beginners experiment with custom curves that rigid sets like the Cutex kit simply can’t form. The catch is the mixed measurement systems: straight and L-shaped rulers read in inches while the rest are metric, so projects drafted from American patterns may require conversion. The flexibility is also a double-edged sword — it’s great for draping over curves, but anyone accustomed to firm drafting tools will find the give frustrating. Individual packaging makes it a practical gift option if you’re buying for someone starting out.
Pros:- Nine pieces cover straight, L-shaped, and French curve needs in one purchase
- Flexible rulers can bend to custom curves without feeling flimsy
- Easy-to-read markings in both metric and inch options
- Individually packaged, making it gift-ready
Cons:- Mixed inch and metric markings force conversions on some projects
- Flexible bodies won’t suit drafters who prefer rigid tools
Best for: Beginners and gift-buyers who want maximum variety and flexible rulers for learning pattern making
Not ideal for: Drafters who prefer rigid tools or work exclusively in imperial units and don’t want metric conversions
- Piece Count:9
- Color:Clear
- Ruler Types:Straight, L-shaped, French curve
- Measurement System:Inches and metric
- Flexibility:Flexible and bendable
- Applications:Pattern making, drafting, drawing, altering
- Packaging:Individual bags
Our verdict“The most beginner-friendly entry point thanks to its variety and flexibility, as long as mixed measurement units won’t slow you down.”
HLZC Imperial Sewing Ruler & French Curve Set, 6-Piece Clear Plastic Rulers
For sewists working from American commercial patterns, this HLZC set solves a problem the Clear Metric 9-piece kit creates: everything here reads in inches only, so there’s no conversion math mid-draft. You get two 24-inch grading rulers, a universal ruler, a 12-inch curve, a 24-inch hip curve, and a measuring gauge — a tighter, more drafting-focused selection than beginner-focused sets that pad out piece counts. The see-through plastic lets you position rulers directly over fabric or pattern paper for accurate adjustments. The compromises are straightforward: no metric markings at all, which rules it out for anyone using European patterns, and the lightweight plastic is less rigid than the aluminum rulers in the Xuhal 4-piece set.
Pros:- Consistent inch-only markings eliminate unit conversion entirely
- Two 24-inch grading rulers plus a measuring gauge cover drafting and alteration work
- Clear plastic allows visibility through to fabric for placement accuracy
- Lightweight pieces are easy to handle for long drafting sessions
Cons:- Inches only — no metric units anywhere in the set
- Lightweight plastic is less rigid than aluminum alternatives
Best for: Sewists drafting from American patterns who want consistent inch-only markings at a low cost
Not ideal for: Anyone working with metric or European patterns, since there are no metric markings
- Pieces:6
- Measurement System:Inches (imperial only)
- Material:Clear plastic
- Included Components:24 in Grading Ruler x2, Universal Ruler, 12 in Curve Ruler, 24 in Hip Curve Ruler, Measuring Gauge
- Color:Clear
- Applications:Pattern making, drafting, alterations
Our verdict“A practical, unit-consistent choice for imperial-pattern drafters who’d rather not juggle conversions.”
Copkim 9-Piece Fashion Design and Sewing Tool Kit
The Copkim kit goes beyond rulers to include a tracing wheel, tailor’s scissors, notcher, and awl — tools you’d normally buy separately after realizing rulers alone don’t complete a pattern-making workflow. Its ruler lineup mirrors the Xuhal 4-piece set closely, with aluminum curve, hip curve, and L-square rulers plus an 18-inch grading ruler and a plastic French curve. That makes it a smarter buy for someone building a workspace from scratch rather than adding to an existing one. The tradeoff: serious sewists will already own scissors and tracing wheels, so much of the kit is redundant, and the tool selection won’t cover specialized needs like buttonhole work. If you already have a stocked sewing kit, the Xuhal set delivers comparable rulers without paying for duplicates.
Pros:- Includes tracing wheel, tailor’s scissors, notcher, and awl alongside five rulers
- Aluminum construction on the curve, hip curve, and L-square rulers
- Clear markings support precise drafting and body measurements
- 18-inch grading ruler adds size-adjustment capability
Cons:- Rulers overlap heavily with tools many sewists already own
- Tool selection won’t cover specialized sewing tasks like buttonhole work
Best for: Newcomers setting up a full pattern-making workspace who need rulers and cutting/tracing tools in one purchase
Not ideal for: Experienced sewists who already own scissors, tracing wheels, and awls — most of the kit would be redundant
- Number of Pieces:9
- Rulers:12-inch aluminum curve ruler, 24-inch aluminum hip curve ruler, 24 x 14-inch aluminum L-square curve ruler, 18-inch grading ruler, clear plastic French curve
- Other Tools:Tracing wheel, tailor’s scissors, notcher, awl
- Materials:Aluminum and clear plastic
- Applications:Pattern making, garment design, tailoring, body measurements, art drawing
- Markings:Clear printed measurements
Our verdict“The most complete launchpad for a beginner’s pattern-making workspace, provided you don’t already own the supporting tools.”
How We Picked
I compared these sets as pattern-drafting tools, focusing on the features that affect how well they support garment work: the range of curve shapes, straight-edge or square tools, measurement units, piece count, and the clarity of the listed kit contents. A larger count only helped a set when its added pieces could plausibly broaden drafting tasks; it did not automatically place that kit above a smaller, more focused option. I also considered whether a set fits a specific workflow, such as inch-based drafting or working with a compact selection of French curves.
The ranking favors versatility for a general pattern-making set, then gives distinct positions to metric and imperial options, beginner-oriented listings, and smaller kits. The HLZC 15-piece set leads on stated assortment size, while Cutex earns a separate role for pairing French curves with an L-square. Sets with similar counts are grouped by their stated unit system and purpose because the available product information does not establish fine differences in material quality or precision. Buyers should check the included shapes and ruler markings in the listing before ordering, especially where product names provide limited detail.

Factors to Consider When Choosing Pattern Making Ruler Set
Choosing a pattern making ruler set is less about collecting the most pieces and more about matching its shapes and markings to the patterns you draft. These factors can help you avoid buying tools that duplicate what you already own or leave a gap in your workflow.
Match the measurement system to your patterns
Start with the units used in the patterns and drafting references you rely on most. A metric ruler set is a natural fit for metric instructions, while an imperial set can keep inch-based drafting direct. Switching units is possible, but repeated conversions add steps and create opportunities for small errors to carry into a garment. If you use both systems, decide whether you need two dedicated sets or can work comfortably from one with clearly marked measurements. Check that the actual markings are legible and useful for your scale before buying.
Choose curve variety for the shapes you draft
French curves support the flowing lines used for areas such as armholes, necklines, and hip shaping, but not every curve serves every job equally well. More pieces can offer more options, yet a large assortment can be harder to store and slower to identify when you are drafting. A smaller set may cover routine work if it includes the shapes you reach for most. Think about the garments you make and which curved seams or pattern adjustments come up repeatedly. Avoid choosing by piece count alone; review the pictured shapes and dimensions when those details are available.
Decide whether you need a square or straight drafting edge
Curve sets and complete drafting kits do different jobs. An L-square can help establish perpendicular lines and square corners, tasks that a French curve cannot replace. If your current ruler already handles straight lines and right angles, a curve-focused set may fill the gap more efficiently. New pattern makers may benefit from a kit with a square because it supports more stages of drafting in one purchase. Check the contents carefully, since a high piece count does not by itself confirm that a square is included.
Balance kit size with your workspace
A compact set takes up less room in a sewing kit and can be easier to carry to a class or shared workspace. Larger collections may cover more drafting situations, but they need storage that keeps the individual shapes visible and protected. Consider where the rulers will live between projects, not just how many tools come in the package. If you draft at a small table, too many pieces can crowd the working area. A useful rule is to prioritize the tools you can identify and reach quickly over extras you may rarely use.
Inspect clarity and fit before relying on a set
Product names do not always tell you enough about ruler thickness, marking contrast, or the size of each curve. Before ordering, inspect the listing images and contents for readable graduations, stated dimensions, and shapes that match your drafting scale. Clear plastic can make the pattern visible underneath, but glare or faint markings may make alignment harder in some lighting. If precision is central to your work, compare the ruler dimensions against a known drafting tool or the measurements specified in your pattern. This check matters more than a long accessory list when you need repeatable lines.
Frequently Asked Questions
Should I choose a 15-piece ruler set or a smaller kit?
Choose the larger set when you draft varied garments and want more curve shapes available without sourcing them separately. A smaller kit can be easier to store and may cover routine work with less sorting. Piece count alone does not show whether the extra tools are useful, so compare the actual shapes and dimensions shown in the listing. If you are still learning, a focused set can make it easier to understand which tools you use most. You can add specialized rulers later if your drafting needs grow.
Is a metric or imperial pattern ruler set better?
Neither system is universally better; the better fit depends on your patterns, references, and drafting habits. Choose metric if most of your instructions use centimeters, and imperial if you work mainly in inches. Using one system consistently cuts down on conversions and makes it easier to check dimensions as you draft. If your projects regularly switch between systems, look closely at the markings and consider whether a second dedicated ruler would help. The HLZC imperial set is the specifically inch-based option in this roundup, while several nine-piece kits are described as metric.
Do I need an L-square as well as French curves?
You need an L-square if your drafting work requires a reliable way to make right angles and square off lines. French curves help shape flowing edges, so they do not cover that same task. If you already own a suitable square, a curve-focused kit may be enough. If you are assembling your first drafting tools, a kit that includes both types can reduce the number of separate purchases. The Cutex kit is the clearly identified option here that pairs French curves with an L-square.
Can a beginner start with a compact four-piece set?
Yes, a compact set can be a sensible start if its shapes match the work you plan to do and you have a straight ruler or square for other drafting tasks. Fewer pieces can make it easier to learn each tool’s purpose without sorting through a large assortment. A four-piece set may feel limiting as you move into a broader range of garment shapes, though. Before buying, check which curves are included and whether the kit fills gaps in your existing tools. Among the listed choices, Cutex offers a four-piece kit with an L-square, while Xuhal is described as a four-piece set with French curves.
What should I check if a product listing gives few ruler details?
Look for a clear image of every included tool, its measurements, and the units marked along the edges. Confirm whether the kit includes straight rulers or a square, since names that emphasize French curves may not tell the whole story. Check for legible graduations and dimensions that suit the scale of your patterns. If a key detail is missing, avoid assuming that the ruler has a particular shape, marking style, or level of precision based on piece count alone. Choosing a listing with clear contents makes it easier to compare it fairly with better-specified alternatives.
Conclusion
For the best overall coverage, I would start with the HLZC 15-piece clear set, provided you have room to store and sort its larger assortment. The best value in a focused kit is the Cutex four-piece set for buyers who need French curves and an L-square together; choose the metric LINXIAO or another nine-piece metric option if unit compatibility and a broader selection matter more. For a beginner, Cutex offers a clear starting point when a square is useful, while the 13- or 15-piece collections suit someone ready to explore more curve options. The best premium-style choice by breadth is HLZC’s 15-piece set, though its listed size does not establish superior material quality. For inch-based drafting, pick the six-piece HLZC imperial set; for a portable, curve-focused kit, compare Xuhal with Cutex based on whether you need the L-square.
