| Best for | Checking which U.S. alias the current Craft Yarn Council table gives a known metric package size before confirming project gauge | Checking an EU supplier's stated VAT number and saving the dated validation response as one identity and invoicing control | Free editorial knitting patterns and techniques |
| Know before using | The reference is not a dimensional measurement, manufacturer inspection, UK or Canadian conversion, steel-hook chart, tool recommendation, yarn assignment, gauge result, or proof that a proposed tool will produce the required fabric. | 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. | 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. |

| What the source establishes | The lookup reproduces the current public Craft Yarn Council metric and U.S. alias rows and follows the Council's warning that company letter and number labels vary; blank aliases remain blank instead of being inferred. | 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. | 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. |
