| Know before using | A suggested match is a data-based shortlist, not proof that the yarn suits the pattern or maker. Yarn records can be incomplete or wrong, prices and availability vary by market, and the site uses affiliate links. Confirm the required gauge, total length, fibre behavior, construction, care, color, dye lot, accessibility, and seller terms, then make and assess a representative swatch before committing. | The record does not create product specifications, prove fit or manufacturability, select materials or construction settings, establish legal compliance, reproduce licensed standards, or replace qualified technical, production, quality, testing, sourcing, logistics, safety, compliance, and legal review. | An account is required and community, publisher, designer, shop, yarn, and project records can vary in currency and accuracy. Search results, ratings, favorites, and project examples do not establish pattern accuracy, yarn availability, seller reliability, fit, gauge, or project suitability. Confirm current files, errata, license, purchase and refund terms, measurements, yarn details, and shop information with the responsible source. |

| What the source establishes | YarnSub's official FAQ says its matching software compares gauge, texture, yarn weight and density, fibre content, and fibre qualities such as drape and softness. Discontinued yarns remain searchable as starting points but are excluded from suggested replacements, and each yarn page provides a route to report source-data problems. | The guide cites current ISO documented-information, garment-measurement, stitch, and seam sources plus current U.S. FTC textile and care-labeling guidance; its working record makes organization-specific requirements, suppliers, evidence, issues, and approvals explicit. | Ravelry's official description identifies a user-driven database of knitting and crochet patterns and yarns, searchable directories for designers, pattern sources, local yarn stores and yarn brands, and a personal notebook for projects, stash, tools, library items, queues, and favorites. Community members and volunteer editors add and maintain the database records. |
