| 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. | A company result is not a blanket approval; confirm the certificate scope, validity, facility, process, product, and transaction documentation for the exact purchase. | The workflow is not a contract or quality certification; local legal duties and technical review may still apply. | 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. |

| 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. | The official GOTS search exposes certified entities by country, field of operation, product category, and certification detail, including processing and trading scopes. | The linked tool or guide is maintained inside Stitch Authority and was checked against its current public interface. | 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. |
