| 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. | The record does not create product specifications, prove fit or manufacturability, select materials or construction settings, establish legal compliance, reproduce licensed standards, or replace qualified technical, production, quality, testing, sourcing, logistics, safety, compliance, and legal review. | 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. |

| 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. | The guide cites current ISO documented-information, garment-measurement, stitch, and seam sources plus current U.S. FTC textile and care-labeling guidance; its working record makes organization-specific requirements, suppliers, evidence, issues, and approvals explicit. | 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. |
