| Best for | Finding a weaving, spinning, or dyeing community | Understanding what a tech pack must control before using a template or releasing work | Planning the current CPSC certificate-data handoff for regulated imports with the importer, finished-product certifier, customs broker, and entry records | Finding the current CYC hook and needle aliases that share one known nominal metric diameter before confirming project gauge |
| Know before using | Coverage reflects affiliated guilds, submitted events, and participating professionals rather than every regional option. HGA states that its paid professional listings are supplied and updated by the professional and are not HGA endorsements. Confirm current contact details, teaching format, accessibility, price, skill level, and safeguarding or insurance needs directly. | 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. | The portal does not decide whether a product requires certification, identify the correct rules or certificate data, classify an entry, replace the current 16 CFR part 1110 text, or reconcile a filing to an actual shipment. Effective dates and workflows differ by entry route; use current CPSC, CBP, customs, product-safety, and legal review. | 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. |

| What the source establishes | The Handweavers Guild of America's current resources page links a searchable affiliate-guild directory, a paid professional-member directory and fiber-art resource guide, book reviews, a public event calendar, scholarships, a quarterly member magazine, and program and store information for weaving, spinning, dyeing, and related fiber arts. | 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. | CPSC operates the eFiling portal with role-specific importer, broker, applicability, Product Registry, regulated-product, laboratory, ACE, FAQ, video, and document-library routes. The certificate final rule took effect July 8, 2026 for covered non-FTZ products, with separate timing for covered FTZ entries. | 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. |
