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. 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

- Access: Free account
- Format: Community
- Source type: Community database

### 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.

## 2. Apparel Grade-Rule & Size-Run Validation Record

Permanent record: <https://stitchauthority.com/directory/grading-guide>
Source page: <https://stitchauthority.com/guides/pattern-grading-explained>

- Primary job: Find patterns & fit
- Area: Patterns & fit
- 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

Auditing inherited grade rules or controlling a new multi-size pattern release from approved targets through sample evidence

### What the source establishes

The guide cites current ISO body-table, size-designation, and garment-measurement boundaries plus two peer-reviewed studies that tested the relationship between conventional grade rules, anthropometric evidence, and garment fit; it requires product-specific target deltas and validation instead of publishing universal increments.

### Know before using

The record does not create a production grade, supply universal increments or breakpoints, validate a CAD file or fit population, reproduce licensed standards, or replace qualified anthropometric, pattern, technical-design, fit, quality, accessibility, safety, statistical, and user-research review.

## 3. QuiltMap

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

- Primary job: Choose materials
- Area: Materials
- For: Makers
- Location or jurisdiction: Global
- Access: Open access
- Format: Directory
- Source type: First-party platform
- Linked page reviewed: 2026-07-15
- Next review due: 2027-01-11

### Best for

Finding quilt-material sellers and adjacent quilting services by country or map

### What the source establishes

QuiltMap describes free public search and free basic listings, community submissions and claims, and country routes covering North America, Europe, Japan, South Korea, and Australia.

### Know before using

Coverage is quilting-specific and uneven by country; businesses can pay for enhanced features, and community or owner updates do not verify inventory, service quality, hours, or availability.

## 4. Compras Brás Fabric & Remnants Directory

Permanent record: <https://stitchauthority.com/directory/compras-bras-fabric-directory>
Source page: <https://www.comprasbras.com.br/tecidos-e-retalhos>

- Primary job: Choose materials
- Area: Materials
- For: Makers
- Location or jurisdiction: Brazil · Latin America & Caribbean
- Access: Open access
- Format: Directory
- Source type: First-party platform
- Linked page reviewed: 2026-07-16
- Next review due: 2027-01-12

### Best for

Building a walkable or call-ahead fabric-shopping list in Brás, then checking retail or wholesale terms, stock, units, and suitability with each business

### What the source establishes

The live category page reported 119 fabric and remnant listings inside a 3,355-business Brás guide, exposes address and contact routes, supports street-level browsing, and states that businesses may submit a free profile for team review.

### Know before using

This is a commercial, self-submission directory for one São Paulo shopping district, not a Brazil-wide shop census or independent material assessment. Listing, wording, contact data, and product keywords may come from the business. Confirm current operation, retail access, stock, fibre content, width, weight, lot, units, minimums, price, payment, accessibility, returns, and travel safety directly. The interface is Portuguese.

## 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.
