### Best for

Free editorial knitting patterns and techniques

### What the source establishes

Knitty currently publishes web-only editorial issues containing original knitting and crochet patterns and articles. Its legal page states that patterns are free for one person's personal use, identifies each designer or author as the copyright holder, and explains that verified pattern corrections are posted in bright pink on the pattern page.

### Know before using

Free access does not grant commercial reproduction or sale rights; uses beyond one personal copy must be resolved with the designer or author. Knitty says it tries to avoid errors but disclaims responsibility for pattern and technique inaccuracies. Check the live page for corrections, verify gauge and measurements, and confirm permission before any commercial use.

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qualitative and quantitative fibre-analysis methods, the published ISO 1833-1 quantitative-analysis principles, ASTM's withdrawn D276 status and reinstatement work item, current FTC U.S. textile-label guidance, and current CPSC clothing-textile flammability guidance.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

## 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.
