| 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. | AFIRM states that its list is guidance, not legal advice, an industry standard of care, or a guarantee of completeness or brand acceptance. It does not replace current law, a customer's stricter RSL, manufacturing-input controls, a product-specific risk and sampling plan, accepted laboratory methods, supplier controls, or performance and safety testing. | It is one curator's intentionally selective, off-Ravelry-oriented database, inventories change, and paid supporters can receive rotating priority placement; verify availability, fibre claims, shipping, and terms directly. | A virtual sample or coloured fit map is not proof of physical fit, comfort, construction quality, manufacturability, or graded-size approval. Results depend on pattern geometry, sewing, avatar measurements and pose, fabric physical-property data, trims, mesh, and simulation settings. Current releases have substantial hardware and learning requirements; validate representative fabrics, bodies, movements, and sewn samples physically. |

| 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. | AFIRM publishes a 2026 multilingual Restricted Substances List for chemicals in finished apparel, footwear, accessories, and related materials, with a material-specific testing matrix. Its FAQ says the list does not cover product-performance testing, distinguishes the finished-product RSL from manufacturing-input lists, and tells suppliers to check each customer's brand-specific requirements and testing acceptance. | The individually researched database offers free listings and sortable yarn, fibre, designer, editor, accessory, and location views; the EU page spans multiple countries and direct seller profiles. | CLO's current product and support documentation covers linked 2D pattern work and 3D garment simulation on avatars, grading review by size, fabric and garment visualization, fit maps for stress, strain, pressure, and tightness, and rendering and presentation output. Current system requirements publish separate Windows and Apple Silicon baselines and higher recommendations for complex simulation and rendering. |
