| 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 foundational library, not yet an exhaustive stitch encyclopedia. | A named organization on a dated partner list does not establish the exact legal entity or facility in scope, current status after the list date, product qualification, approved chemical article, process coverage, testing, delivery, performance, commercial fit, or permission for a particular claim or label. Use the separate current product, textile, chemical, criteria, and claim route that matches the decision. |

| Source and review | |||
| 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. Current terms state that the free plan requires no card, paid upgrades start billing immediately, cancellation retains paid features through the current cycle, and the account then returns to free features. | The linked tool or guide is maintained inside Stitch Authority and was checked against its current public interface. | bluesign's current downloads page links general and brand-specific System Partner lists dated July 1, 2026. The general list separates brands and retailers, chemical suppliers, and manufacturers. The same official page routes product verification, the Textiles Guide, the Chemical Finder, criteria, and bluepass label and claim guidance as distinct checks. |
