| Best for | Free editorial knitting patterns and techniques | Understanding what a tech pack must control before using a template or releasing work | Finding or checking paper-based packaging and hangtag suppliers with PEFC chain-of-custody scope | Auditing inherited grade rules or controlling a new multi-size pattern release from approved targets through sample evidence |
| 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. | 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. | A chain-of-custody record applies only to the named organization and scope; verify the exact product claim, current status, supplier role, artwork approval, and transaction documentation for each order. | 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. |

| 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. | 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. | PEFC describes the database as a current discovery and verification route for certified organizations, certificate validity, countries, product scope, sourcing, and due diligence. | 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. |
