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. Controlled Tech Pack Orientation

Permanent record: <https://stitchauthority.com/directory/tech-pack>
Source page: <https://stitchauthority.com/guides/what-is-a-tech-pack>

- Primary job: Source production
- Area: Production
- For: Apparel brands
- Location or jurisdiction: Global
- Access: Open access
- Format: Stitch Authority
- Source type: Stitch Authority
- Linked page reviewed: 2026-07-16
- Next review due: 2027-07-16

### Best for

Understanding what a tech pack must control before using a template or releasing work

### What the source establishes

The guide cites current ISO sources for documented-information, garment-measurement, stitch, and seam boundaries plus current U.S. FTC textile and care-labeling guidance; it explicitly separates those authorities from product-specific technical and market decisions.

### Know before using

An orientation rather than a completed product record; it does not supply a universal format, licensed standard content, measurements, tolerances, construction settings, labels, approvals, compliance conclusion, or product-release authority.

## 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. The Cloth Library

Permanent record: <https://stitchauthority.com/directory/cloth-library>
Source page: <https://stitchauthority.com/fabric>

- Primary job: Choose materials
- Area: Materials
- For: Both
- Location or jurisdiction: Global
- Access: Open access
- Format: Stitch Authority
- Source type: Stitch Authority
- Linked page reviewed: 2026-07-16
- Next review due: 2027-07-16

### Best for

Starting a fabric decision before purchase or cutting

### What the source establishes

All 50 current cloth entries meet the source-reviewed content contract. The public index, cards, permanent pages, and site search expose that state, while the repository audit enforces a current review date, substantive scope, decision boundaries, and at least three external sources. The migrated cases cover fibre and family representations, woven and knitted construction, open nets, raised and dimensional surfaces, mass, thickness, drape, elasticity, colour, seams, pressing, care state, supports, and complete-product decisions.

### Know before using

Source-reviewed describes the page and its cited decision boundaries. It does not authenticate a commercial roll, seller claim, fibre percentage, construction, finish, performance result, machine setting, care route, compliance status, supplier, or product fitness. Internal browse bands are navigation labels, not textile standards or product classes; an entry without a usable listed mass range is unclassified. Check the actual article, seller data, care label, equipment instructions, representative assemblies, applicable rules, and project requirements before deciding.

## 4. 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
- Next review due: 2027-01-17

### 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.

## 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.
