- Primary job: Find patterns & fit
- Area: Patterns & fit
- For: Both
- Location or jurisdiction: Global

### Best for

2D patternmaking and grading with public plan tiers

### What the source establishes

Tukatech's current TUKAcad page publishes monthly Learning and Professional editions for digital patternmaking and grading, with a higher tier adding marker making, data import and export, digitizing, cut-data optimization, and yield reports. It discloses plan limits on pattern pieces, graded sizes, and marker dimensions, plus built-in help, block templates, a trial, Windows requirements, and the Windows-on-Mac route.

### Know before using

TUKAcad is Windows software; the official Mac route requires a separate virtual Windows environment. Pattern-piece, graded-size, marker, import and export, digitizing, and production-output capabilities vary materially by paid tier. A CAD file or marker report does not prove fit or factory readiness, so verify formats, grade rules, seam and production data, hardware, training, and downstream compatibility before subscribing.

### Best for

Following a structured classroom introduction to womenswear block development, muslin test fitting, fit correction, and basic flat-pattern manipulation

### What the source establishes

CBSE's official publication index links the Class XII Fashion Studies textbook. Its Basic Pattern Development chapter covers body and dress-form measurement, size relationships, patternmaking tools and terms, fit and balance, muslin test fitting, block correction, bodice, sleeve and skirt blocks, seam allowances, grain lines, notches, necklines, collars, and dart manipulation. The stated learning outcomes include developing blocks from charts and body measurements, testing fit, correcting the pattern, and developing simple designs from basic blocks.

### Know before using

This is a classroom textbook with particular womenswear exercises, charts, figures, terminology, units, and drafting methods. It is not a universal body, block, grading, or sizing system; current industry certification; or proof of fit for an individual wearer or product. Some content and examples predate the current review. Verify the intended body data, measurement protocol, ease, material, seam and construction rules, accessibility, current curriculum status, and representative sewn fit independently.

## 3. YarnSub

Permanent record: <https://stitchauthority.com/directory/yarnsub>
Source page: <https://yarnsub.com/>

- Primary job: Choose materials
- Area: Yarn
- For: Makers
- Location or jurisdiction: Global
- Access: Open access
- Format: Reference
- Source type: First-party platform
- Linked page reviewed: 2026-07-28
- Next review due: 2027-01-24

### Best for

Building a substitution shortlist for a discontinued or unavailable yarn before checking quantity, availability, and a representative swatch

### What the source establishes

YarnSub's official FAQ says its matching software compares gauge, texture, yarn weight and density, fibre content, and fibre qualities such as drape and softness. Discontinued yarns remain searchable as starting points but are excluded from suggestions. Result filters can exclude animal, animal-derived, synthetic, or plant fibre groups and use a subjective $ to $$$$$ price indicator. The site does not accept user-entered yarn details, individual shade cards, or expose an API. Each yarn page provides a data-issue route.

### Know before using

A suggested match is a data-based shortlist, not proof that the yarn suits the pattern or maker. Records can be incomplete or wrong, price bands are approximate, availability varies by country and seller, and shade-level matching is unavailable. YarnSub says affiliate status does not change suggestions, but equally rated matches are ordered by brand popularity. Confirm required gauge, total length, fibre behavior, construction, care, colour, dye lot, accessibility, price, availability, and seller terms, then make and assess a representative swatch before committing.

### Account, payment, and exit

- Access scope: Maker comparing a replacement for a named yarn before buying.
- Before an account: Search a named yarn, inspect suggested substitutes, and filter by fibre and approximate price band without creating an account.
- Free-account boundary: The checked core substitution route does not require an account, and the FAQ does not offer user-entered yarn records.
- Payment boundary: No subscription is presented for the core route. Affiliate retailer links and optional donations help fund the site; equal-rated matches are ordered by brand popularity.
- Cancellation or exit: There is no account or recurring plan to cancel for the core route. The newsletter has a separate unsubscribe link.
- Saved work and data: YarnSub does not expose an API and does not accept user-entered yarn details. Use the data-issue link on a yarn page for corrections.

## 4. Optitex 2D/3D Pattern Design

Permanent record: <https://stitchauthority.com/directory/optitex-pds>
Source page: <https://optitex.com/products/2d-and-3d-cad-software/>

- Primary job: Find patterns & fit
- Area: Patterns & fit
- For: Apparel brands
- Location or jurisdiction: Global
- Access: Quote-based
- Format: Software
- Source type: First-party platform
- Linked page reviewed: 2026-07-21
- Next review due: 2027-01-17

### Best for

Integrated pattern, marker, and 3D production workflows

### What the source establishes

Optitex's current page describes 2D pattern creation, grading, verification, Tech Pack Essentials, marker creation and nesting, cut and plot output, 3D virtual samples, fabric simulation, colour and print placement, tension maps, and avatar editing. Its support page lists native and standard CAD interchange routes and states that Optitex does not support macOS.

### Know before using

Pricing is not public, modules and system requirements must be confirmed, and macOS is not supported. Vendor accuracy and fit language does not prove results for an actual product. Pilot native and exchanged files with the receiving supplier, calibrated materials, approved blocks and grade rules, marker and output devices, tech-pack fields, training, version control, and risk-appropriate physical fit and production checks.

## Next checks

1. Remove any route whose audience, jurisdiction, access, or scope does not match the job.
2. Open the permanent record and source page for every remaining route.
3. Recheck facts that can change after the listed review date.
4. Verify project-specific capability, terms, test evidence, and legal requirements with the responsible source or provider.
5. Record the reason for the final choice outside Stitch Authority.
