| Best for | Finding the current CYC hook and needle aliases that share one known nominal metric diameter before confirming project gauge | Finding or checking paper-based packaging and hangtag suppliers with PEFC chain-of-custody scope | Coordinating an independent sewing-pattern test |
| 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 chain-of-custody record applies only to the named organization and scope; verify the exact product claim, current status, supplier role, artwork approval, and transaction documentation for each order. | The interface and plan description do not prove tester reach, completion, feedback quality, fit validity, export quality, uptime, support, or suitability for an established release process. Measurements and photos can be sensitive personal data. Run a non-critical pilot, review the current privacy and service terms, define consent and photo rights, test exports and deletion, and keep pattern approval and release responsibility with the designer. |

| 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. | PEFC describes the database as a current discovery and verification route for certified organizations, certificate validity, countries, product scope, sourcing, and due diligence. | Pattern Testers currently offers application intake, tester selection, feedback, photos, approvals, issue tracking, revisions, a reusable tester directory, and release deadlines. The public pricing page shows a limited free plan and paid Pro and Business tiers. Its June 2026 privacy policy lists names, email addresses, measurements, photos, feedback, application history, and assignments among the data processed. |
