| Best for | Finding the current CYC hook and needle aliases that share one known nominal metric diameter before confirming project gauge | Searching global apparel and textile production capabilities | Searching current and out-of-print sewing patterns | Building a US manufacturer shortlist |
| 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. | The company count is a changing platform claim. Search fields, profiles, certificates, locations, and account access do not independently verify the legal entity, factory ownership, capability, capacity, certificate validity or scope, compliance performance, delivery, or project fit. Confirm the site and subcontracting, credentials with issuers, samples, audits when appropriate, specifications, contracts, and commercial terms. | Community members add and quality-control the records, so confirm sizing, measurements, fabric suggestions, format, availability, errata, license, and purchase terms with the designer or publisher. Adding an entry to a stash does not provide the pattern files. Saved searches and private PDF storage are paid Plus features, and a listing or review does not establish pattern accuracy or fit. | CFDA states that it collects basic business information but does not audit, certify, or monitor the listed facilities, and that inclusion is not endorsement, recommendation, a quality guarantee, or CFDA membership. Verify identity, ownership, capabilities, materials, equipment, minimums, capacity, price, lead time, quality systems, labor and environmental practices, compliance, references, contracts, and product fit directly before selection. |

| 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. | FOURSOURCE's current public network page presents an operator-reported global company count and country or territory search. It says logged-in users can narrow results by compliance certificates, product groups, fabric types, target groups, minimum order quantities, and other fields, with a free-trial and supplier sign-up route. | Threadloop's official guide describes an independent, fully crowdsourced database covering available and out-of-print sewing patterns. Its search supports pattern type, fabric type, age group, body type, cup size, level, format, file features, language, measurements, availability, and other filters; members can also track a stash, wishlist, projects, reviews, and discussions. Current terms state that the free plan requires no card, paid upgrades start billing immediately, cancellation retains paid features through the current cycle, and the account then returns to free features. | CFDA publishes this as an open-access directory of United States fashion contract manufacturers with no registration required. The page supports sorting by service, product, category, and sample or production minimums. Its current notice says the application link is under repair and directs join, update, removal, and other inquiries to supplychain@cfda.com. |
