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. Pattern Testers

Permanent record: <https://stitchauthority.com/directory/pattern-testers>
Source page: <https://patterntesters.com/>

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

### Best for

Coordinating an independent sewing-pattern test

### What the source establishes

Pattern Testers currently offers application intake, tester selection, feedback, photos, approvals, issue tracking, revisions, a reusable tester directory, and release deadlines. The public pricing page shows a limited free plan and paid Pro and Business tiers. Its June 2026 privacy policy lists names, email addresses, measurements, photos, feedback, application history, and assignments among the data processed.

### Know before using

The interface and plan description do not prove tester reach, completion, feedback quality, fit validity, export quality, uptime, support, or suitability for an established release process. Measurements and photos can be sensitive personal data. Run a non-critical pilot, review the current privacy and service terms, define consent and photo rights, test exports and deletion, and keep pattern approval and release responsibility with the designer.

## 2. 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.

## 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: 2026-07-21
- Next review due: 2027-01-17

### Best for

Replacing a discontinued or unavailable yarn

### 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 suggested replacements, and each yarn page provides a route to report source-data problems.

### Know before using

A suggested match is a data-based shortlist, not proof that the yarn suits the pattern or maker. Yarn records can be incomplete or wrong, prices and availability vary by market, and the site uses affiliate links. Confirm the required gauge, total length, fibre behavior, construction, care, color, dye lot, accessibility, and seller terms, then make and assess a representative swatch before committing.

## 4. EU PPE Harmonised Standards List

Permanent record: <https://stitchauthority.com/directory/eu-ppe-harmonised-standards>
Source page: <https://single-market-economy.ec.europa.eu/single-market/goods/european-standards/harmonised-standards/personal-protective-equipment_en>

- Primary job: Check standards
- Area: Standards
- For: Apparel brands
- Location or jurisdiction: European Union
- Access: Open access
- Format: Reference
- Source type: Government guidance
- Linked page reviewed: 2026-07-16
- Next review due: 2026-10-14

### Best for

Checking whether a PPE standard reference is currently published or scheduled for withdrawal before obtaining the licensed standard and mapping its covered requirements

### What the source establishes

The Commission page identifies Implementing Decision (EU) 2026/1279 of June 12, 2026 as the current Official Journal publication for PPE harmonised standards. The decision's Annex I lists EN ISO 20471:2013, corrected version 2013-06-01, together with EN ISO 20471:2013/A1:2016 for high-visibility clothing at the checked date.

### Know before using

The Commission says its consolidated summary is informational and may not be complete at every moment; legal effect comes from Official Journal publications. A listed reference does not select the standard for a product, reproduce licensed technical content, cover every essential requirement, prove conformity, or authorize a performance class or CE mark. Recheck the current OJEU publication, obtain the correct controlled standard, and document product-specific coverage and evidence.

## 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.
