| Know before using | 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. | A company result is not a blanket approval; confirm the certificate scope, validity, facility, process, product, and transaction documentation for the exact purchase. | Source-reviewed describes the page and its cited decision boundaries. It does not authenticate a commercial roll, seller claim, fibre percentage, construction, finish, performance result, machine setting, care route, compliance status, supplier, or product fitness. Internal browse bands are navigation labels, not textile standards or product classes; an entry without a usable listed mass range is unclassified. Check the actual article, seller data, care label, equipment instructions, representative assemblies, applicable rules, and project requirements before deciding. | 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. |

| What the source establishes | 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. | The official GOTS search exposes certified entities by country, field of operation, product category, and certification detail, including processing and trading scopes. | All 50 current cloth entries meet the source-reviewed content contract. The public index, cards, permanent pages, and site search expose that state, while the repository audit enforces a current review date, substantive scope, decision boundaries, and at least three external sources. The migrated cases cover fibre and family representations, woven and knitted construction, open nets, raised and dimensional surfaces, mass, thickness, drape, elasticity, colour, seams, pressing, care state, supports, and complete-product decisions. | 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. |
