| 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. | 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. | A valid VAT number is not proof of manufacturing capability, facility ownership, authorized bank instructions, product origin, tax advice, quality, capacity, certification, labor conditions, or delivery; names and addresses may not be returned for every country, and temporary database outages occur. |

| 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. | 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. | VIES is the European Commission's online VAT Information Exchange System interface for querying national VAT databases to determine whether a submitted number is valid for intra-EU cross-border trade at the time of the request. |
