| Know before using | Free access does not grant commercial reproduction or sale rights; uses beyond one personal copy must be resolved with the designer or author. Knitty says it tries to avoid errors but disclaims responsibility for pattern and technique inaccuracies. Check the live page for corrections, verify gauge and measurements, and confirm permission before any commercial use. | 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 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. | A measurement-generated draft is a starting block, not independent evidence of body capture, comfort, mobility, balance, garment ease, or production fit. The result depends on measurement accuracy, supported ranges, formula assumptions, selected options, and output handling. Review the service's privacy terms before storing body data and sew a representative toile before design, grading, or production use. |

| What the source establishes | Knitty currently publishes web-only editorial issues containing original knitting and crochet patterns and articles. Its legal page states that patterns are free for one person's personal use, identifies each designer or author as the copyright holder, and explains that verified pattern corrections are posted in bright pink on the pattern page. | 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. | 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. | PatternLab London's current drafting page says a user creates a measurement profile, selects a basic block or sloper, adjusts fit, dart placement, length, seam allowance, and sleeve options, then downloads the generated result as tiled PDF, AI, or SVG. The live catalogue names bodice, dress, trouser, and stretch blocks and displays a price before purchase. |
