| Know before using | 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. | 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. | Free access does not grant commercial reproduction or sale rights; uses beyond one personal copy must be resolved with the designer or author. Knitty says it tries to avoid errors but disclaims responsibility for pattern and technique inaccuracies. Check the live page for corrections, verify gauge and measurements, and confirm permission before any commercial use. | The record does not reproduce licensed code diagrams, verify a user's proposed code, authorize an ISO and ASTM crosswalk, select a construction, set stitch density or machine settings, prove supplier repeatability or performance, or replace the licensed standards and qualified construction, sewing, production, testing, safety, and quality review. |

| What the source establishes | 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. | 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. | Knitty currently publishes web-only editorial issues containing original knitting and crochet patterns and articles. Its legal page states that patterns are free for one person's personal use, identifies each designer or author as the copyright holder, and explains that verified pattern corrections are posted in bright pink on the pattern page. | The guide cites the current public scopes and statuses of ISO 4915:1991, ISO 4916:1991, and ASTM D6193-16(2025), plus current seam-failure and seam-tensile methods; it keeps classification, translation, complete process definition, physical verification, and performance evidence separate. |
