| 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. | A suggested match is a data-based shortlist, not proof that the yarn suits the pattern or maker. Yarn records can be incomplete or wrong, prices and availability vary by market, and the site uses affiliate links. Confirm the required gauge, total length, fibre behavior, construction, care, color, dye lot, accessibility, and seller terms, then make and assess a representative swatch before committing. | 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. |

| 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. | YarnSub's official FAQ says its matching software compares gauge, texture, yarn weight and density, fibre content, and fibre qualities such as drape and softness. Discontinued yarns remain searchable as starting points but are excluded from suggested replacements, and each yarn page provides a route to report source-data problems. | 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. |
