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 Grading & 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: 2026-07-27
- Next review due: 2027-07-27

### 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.

## 2. Unknown Textile Identification & Evidence Record

Permanent record: <https://stitchauthority.com/directory/unknown-textile-identification-record>
Source page: <https://stitchauthority.com/guides/how-to-identify-fabric-burn-test>

- 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

Investigating an unknown textile without using flame, smoke, odor, or residue as composition, flammability, care, safety, or compliance proof

### What the source establishes

The guide cites current AATCC qualitative and quantitative fibre-analysis methods, the published ISO 1833-1 quantitative-analysis principles, ASTM's withdrawn D276 status and reinstatement work item, current FTC U.S. textile-label guidance, and current CPSC clothing-textile flammability guidance.

### Know before using

The record does not identify a submitted textile, provide a home burn procedure, turn an observation into a fibre or blend result, choose a laboratory method, establish flammability or market compliance, validate a care instruction, or replace qualified laboratory, textile, conservation, safety, compliance, and legal review.

## 3. FreeSewing

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

- Primary job: Find patterns & fit
- Area: Patterns & fit
- For: Makers
- Location or jurisdiction: Global
- Access: Open access
- Format: Software
- Source type: Open-source project
- Linked page reviewed: 2026-07-21
- Next review due: 2027-01-17

### Best for

Custom-fit home sewing patterns

### What the source establishes

FreeSewing's official documentation says the browser editor drafts a selected design in real time from a measurement set rather than scaling or grading a standard-size pattern. Users can adjust design options and export the generated result, including as PDF; saving the pattern to an account is optional and is used to revisit it later.

### Know before using

A generated pattern is not independent fit evidence or a production-ready graded block. The result still depends on accurate measurements, the selected design and options, ease assumptions, fabric behavior, construction, and representative test garments. An account stores saved patterns and measurement sets, so review the platform's privacy terms before retaining personal measurements.

## 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.
