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.

### 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. FOURSOURCE Supplier Network

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

- Linked page reviewed: 2026-07-21

### Best for

Searching global apparel and textile production capabilities

### What the source establishes

FOURSOURCE's current public network page presents an operator-reported global company count and country or territory search. It says logged-in users can narrow results by compliance certificates, product groups, fabric types, target groups, minimum order quantities, and other fields, with a free-trial and supplier sign-up route.

### Know before using

The company count is a changing platform claim. Search fields, profiles, certificates, locations, and account access do not independently verify the legal entity, factory ownership, capability, capacity, certificate validity or scope, compliance performance, delivery, or project fit. Confirm the site and subcontracting, credentials with issuers, samples, audits when appropriate, specifications, contracts, and commercial terms.

## 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.
