| Best for | Finding the current CYC hook and needle aliases that share one known nominal metric diameter before confirming project gauge | Checking a named facility's current WRAP certification or discovering listed production units | Finding independent EU yarn or fibre dyers with off-Ravelry purchase routes |
| Know before using | A shared nominal diameter does not make a knitting needle and crochet hook interchangeable or predict equal gauge or fabric. The reference is not a physical measurement, manufacturer inspection, UK or Canadian conversion, steel-hook chart, tool recommendation, yarn assignment, or project approval. | A listed facility and its certification status do not establish product quality, capacity, availability, upstream coverage, whole-chain performance, buyer fit, or the scope and result of a particular order. Confirm the exact legal entity and production unit, current certificate and scope, product and process capability, capacity, monitoring evidence, corrective actions, references, and commercial terms directly. | 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. |

| What the source establishes | Rechecked July 28, 2026. The lookup reproduces the current public Craft Yarn Council metric and U.S. alias rows, aligns hooks and needles only when their nominal millimetre value matches, and leaves missing rows or aliases unfilled. | WRAP states that thousands of WRAP-certified facilities operate worldwide and that buyers can use the public route to verify a named factory's certification or find certified manufacturers for apparel, footwear, sewn and leather goods, textiles, and related products. The page exposes certified facilities and monitoring firms as separate routes. | 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. |
