### Best for

Chemical-input controls during manufacturing

### What the source establishes

ZDHC's current scope defines the MRSL as restrictions on intentional use of listed substances in commercial chemical formulations for textile, leather, rubber, foam, adhesive, and trim processing. Covered inputs include cleaners, dyes, auxiliaries, coatings, finishing agents, maintenance, wastewater-treatment, sanitation, and pest-control chemicals. ZDHC's help centre identifies version 3.1 as the current official MRSL and distinguishes it from restrictions measured in finished products.

### Know before using

The MRSL controls manufacturing inputs within its stated scope. It does not by itself prove a facility's chemical inventory, implementation, worker protection, emissions, wastewater performance, formulation conformance, or finished-product compliance. Verify the current version, law, brand program, safety rules, chemical-product certificates and status, facility records, and finished-product RSL and testing requirements.

## 2. Australia Basic Patternmaking Competency

### 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.

## 3. Threadloop Sewing Pattern Database

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

- Primary job: Find patterns & fit
- Area: Patterns & fit
- For: Makers
- Location or jurisdiction: Global
- Access: Free account
- Format: Community
- Source type: Community database
- Linked page reviewed: 2026-07-21
- Next review due: 2027-01-17

### Best for

Searching current and out-of-print sewing patterns

### What the source establishes

Threadloop's official guide describes an independent, fully crowdsourced database covering available and out-of-print sewing patterns. Its search supports pattern type, fabric type, age group, body type, cup size, level, format, file features, language, measurements, availability, and other filters; members can also track a stash, wishlist, projects, reviews, and discussions.

### Know before using

Community members add and quality-control the records, so confirm sizing, measurements, fabric suggestions, format, availability, errata, license, and purchase terms with the designer or publisher. Adding an entry to a stash does not provide the pattern files. Saved searches and private PDF storage are paid Plus features, and a listing or review does not establish pattern accuracy or fit.

## 4. TUKAcad

Permanent record: <https://stitchauthority.com/directory/tukacad>

- 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
- Next review due: 2027-01-17

### 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.

## 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.
