| 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. | Patternmaking knowledge, controlled measurement files, production conventions, and sewn fit testing are still required. The software does not validate body measurements, ease, balance, grading rules, fabric behavior, construction, or product fit. The project currently labels its user wiki manual as needing updates, so confirm current commands and file behavior against the installed release and active support channels. | 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. |

Contributor, claimed, and partner fields have different provenance and update paths. |
| 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 maintained Seamly2D repository identifies the application as GPLv3+ open-source patternmaking software for Windows, macOS, and Linux. It reads multi-size measurement files for standardized sizes and individual measurement files for custom-fit work, publishes downloadable builds and releases, and links an active website and user forum. | 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. |
