| Know before using | The platform combines stakeholder-contributed, public-list, facility-claimed, and partner data with different origins and update paths. A facility record, contributor connection, claim, certification field, or shared OS ID is not a quality endorsement, ownership finding, complete supplier relationship, current capacity statement, or due-diligence result. Inspect the source badges, contributors, dates, duplicates, claimed fields, and linked evidence, then verify the facility and intended business relationship directly. | The interface and plan description do not prove tester reach, completion, feedback quality, fit validity, export quality, uptime, support, or suitability for an established release process. Measurements and photos can be sensitive personal data. Run a non-critical pilot, review the current privacy and service terms, define consent and photo rights, test exports and deletion, and keep pattern approval and release responsibility with the designer. | 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. |

| Source and review | ||||
| What the source establishes | Open Supply Hub's current guide supports facility-name or OS ID, contributor, location, sector, parent-company, facility-type, processing-type, product-type, and worker-count searches, with contributor information visible on facility data. Manual search is open, a free account supports bounded data downloads, and paid services cover larger or programmatic access. | Pattern Testers currently offers application intake, tester selection, feedback, photos, approvals, issue tracking, revisions, a reusable tester directory, and release deadlines. The public pricing page shows a limited free plan and paid Pro and Business tiers. Its June 2026 privacy policy lists names, email addresses, measurements, photos, feedback, application history, and assignments among the data processed. | 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. |
