Know before usingThe record does not verify a yarn label, certify fibre or origin, provide a regional ply crosswalk, predict exact quantity or cost, approve care, establish allergy safety, or prove finished fit, wear, durability, availability, or project success.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.The record does not create a production grade, supply universal increments or breakpoints, validate a CAD file or fit population, reproduce licensed standards, or replace qualified anthropometric, pattern, technical-design, fit, quality, accessibility, safety, statistical, and user-research review.

Source and review
What the source establishesThe guide cites current Craft Yarn Council weight-system, FAQ, WPI, and hook-and-needle guidance plus current ASTM tex-designation and ISO yarn-linear-density sources; it distinguishes voluntary craft category, subjective screen, package quantity, measured property, finished gauge, and project decision.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 guide cites current ISO body-table, size-designation, and garment-measurement boundaries plus two peer-reviewed studies that tested the relationship between conventional grade rules, anthropometric evidence, and garment fit; it requires product-specific target deltas and validation instead of publishing universal increments.
