This file preserves the published decision metadata for the selected routes. It is not a recommendation, provider approval, compliance decision, or record of project-specific due diligence.

## 1. CLO

Permanent record: <https://stitchauthority.com/directory/clo-3d>
Source page: <https://www.clo3d.com/en/clo/features>

- Primary job: Find patterns & fit
- Area: Patterns & fit
- For: Both
- Location or jurisdiction: Global
- Access: Paid
- Format: Software
- Source type: First-party platform
- Linked page reviewed: 2026-07-21

### Best for

Individual and team 3D garment prototyping

### What the source establishes

CLO's current product and support documentation covers linked 2D pattern work and 3D garment simulation on avatars, grading review by size, fabric and garment visualization, fit maps for stress, strain, pressure, and tightness, and rendering and presentation output. Current system requirements publish separate Windows and Apple Silicon baselines and higher recommendations for complex simulation and rendering.

### Know before using

A virtual sample or coloured fit map is not proof of physical fit, comfort, construction quality, manufacturability, or graded-size approval. Results depend on pattern geometry, sewing, avatar measurements and pose, fabric physical-property data, trims, mesh, and simulation settings. Current releases have substantial hardware and learning requirements; validate representative fabrics, bodies, movements, and sewn samples physically.

## 2. YarnSub

- Primary job: Choose materials

- For: Makers
- Location or jurisdiction: Global

### 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.

## 3. Australia Basic Patternmaking Competency

Permanent record: <https://stitchauthority.com/directory/australia-basic-patternmaking-competency>
Source page: <https://training.gov.au/training/details/MSTAT3002>

- Primary job: Find patterns & fit
- Area: Patterns & fit
- For: Both
- Location or jurisdiction: Australia · Oceania
- Access: Open access
- Format: Reference
- Source type: Official registry
- Linked page reviewed: 2026-07-16
- Next review due: 2026-10-14

### Best for

Scoping training, hiring, assessment, or evidence requirements for basic textile-product pattern development and testing in Australia

### What the source establishes

Australia's National Training Register publishes current unit MSTAT3002, Develop patterns using basic patternmaking principles. The release document describes interpreting textile-product design specifications, considering fabric performance, selecting tools and equipment, developing patterns, testing the result, and making alterations. Release 1 was generated December 22, 2022 and merged two earlier units. Current Australian apparel and live-production qualifications list MSTAT3002, while the current diploma also exposes advanced individual-fit, alteration, and fit-model units.

### Know before using

This is a competency and assessment reference, not an instructional course, pattern file, qualification by reading, provider recommendation, professional license, or proof that a person can perform the work. The route does not establish enrollment availability, teaching quality, fees, support, recognition outside Australia, or product-specific fit. Confirm the current unit status, packaging rules, prerequisites, registered provider, assessment conditions, local requirements, and actual evidence before relying on it.

## 4. Seam Allowance Converter

Permanent record: <https://stitchauthority.com/directory/seam-allowance>
Source page: <https://stitchauthority.com/tools/seam-allowance-converter>

- Primary job: Find patterns & fit
- Area: Patterns & fit
- For: Both
- Location or jurisdiction: Global
- Access: Open access
- Format: Stitch Authority
- Source type: Stitch Authority
- Linked page reviewed: 2026-07-28

### Best for

Translating a seam allowance already stated by a pattern or controlled specification

### What the source establishes

NIST states that one inch is exactly 25.4 millimetres, and the SI decimal relationship makes one centimetre equal to 10 millimetres. The tool uses those factors, displays rounded equivalents, exposes the size difference to the nearest 1/16 inch when converting to inches, and preserves valid value, source-unit, and target-unit state in the URL.

### Know before using

This is a unit-translation reference. It does not select, approve, or change a seam allowance; establish a universal fraction; interpret an unstated cutting or stitching line; or replace the exact pattern version, controlled specification, material and seam evidence, sample, production method, equipment, tolerance, or release authority.

## 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.
