| Best for | Finding the current CYC hook and needle aliases that share one known nominal metric diameter before confirming project gauge | Checking GOTS certification records | Finding quilt-material sellers and adjacent quilting services by country or map | Understanding what a tech pack must control before using a template or releasing work |
| 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 company result is not a blanket approval; confirm the certificate scope, validity, facility, process, product, and transaction documentation for the exact purchase. | Coverage is quilting-specific and uneven by country; businesses can pay for enhanced features, and community or owner updates do not verify inventory, service quality, hours, or availability. | An orientation rather than a completed product record; it does not supply a universal format, licensed standard content, measurements, tolerances, construction settings, labels, approvals, compliance conclusion, or product-release authority. |

| 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. | The official GOTS search exposes certified entities by country, field of operation, product category, and certification detail, including processing and trading scopes. | QuiltMap describes free public search and free basic listings, community submissions and claims, and country routes covering North America, Europe, Japan, South Korea, and Australia. | The guide cites published ISO sources for documented-information, garment-measurement, stitch, and seam boundaries plus current U.S. FTC textile and care-labeling guidance; it discloses that ISO 10013:2021's 2026 systematic review is at close-of-review stage and separates every cited authority from product-specific technical and market decisions. |
