| Know before using | A suggested match is a data-based shortlist, not proof that the yarn suits the pattern or maker. Records can be incomplete or wrong, price bands are approximate, availability varies by country and seller, and shade-level matching is unavailable. YarnSub says affiliate status does not change suggestions, but equally rated matches are ordered by brand popularity. Confirm required gauge, total length, fibre behavior, construction, care, colour, dye lot, accessibility, price, availability, and seller terms, then make and assess a representative swatch before committing. | 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. | A generated pattern is not independent fit evidence or a production-ready graded block. The result still depends on accurate measurements, the selected design and options, ease assumptions, fabric behavior, construction, and representative test garments. An account stores saved patterns and measurement sets, so review the platform's privacy terms before retaining personal measurements. | The platform is for knit and crochet rather than sewing, and a profile, application, rating, or platform listing does not prove technical competence, availability, identity, or fit for a project. Prices and plan limits can change. Define the test or edit scope, sizes, yarn, deadlines, compensation, confidentiality, intellectual property, file handling, expected feedback, and dispute process in writing before work starts. |

| Before an account | Search a named yarn, inspect suggested substitutes, and filter by fibre and approximate price band without creating an account. | Not yet reviewed at this level. | Not yet reviewed at this level. | Browse public open testing calls and the provider's feature and pricing pages without signing in. |
| Free-account boundary | The checked core substitution route does not require an account, and the FAQ does not offer user-entered yarn records. | Not yet reviewed at this level. | Not yet reviewed at this level. | A free signup lets people look around, and testers participate without a platform charge. Designers and tech editors face different role boundaries. |
| Payment boundary | No subscription is presented for the core route. Affiliate retailer links and optional donations help fund the site; equal-rated matches are ordered by brand popularity. | Not yet reviewed at this level. | Not yet reviewed at this level. | Designers can pay per call or job, buy non-expiring credits, or subscribe monthly. Tech editors need a separate monthly subscription to apply for jobs. |
| Cancellation or exit | There is no account or recurring plan to cancel for the core route. The newsletter has a separate unsubscribe link. | Not yet reviewed at this level. | Not yet reviewed at this level. | The pricing page says monthly subscriptions can be canceled at any time, but it does not state when paid access ends or what happens to active tests or applications. |
| Saved work and data | YarnSub does not expose an API and does not accept user-entered yarn details. Use the data-issue link on a yarn page for corrections. | Not yet reviewed at this level. | Not yet reviewed at this level. | Designers can download pattern-test feedback as CSV or XLSX. The checked pages do not establish a full account export or deletion route. |
| Source and review | ||||
| 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 suggestions. Result filters can exclude animal, animal-derived, synthetic, or plant fibre groups and use a subjective $ to $$$$$ price indicator. The site does not accept user-entered yarn details, individual shade cards, or expose an API. Each yarn page provides a data-issue route. | 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. | FreeSewing's official documentation says the browser editor drafts a selected design in real time from a measurement set rather than scaling or grading a standard-size pattern. Users can adjust design options and export the generated result, including as PDF; saving the pattern to an account is optional and is used to revisit it later. | Yarnpond's current pages let knit and crochet designers publish public or private testing calls, select applicants, communicate with test teams, set milestones, collect feedback, post sample-making calls, and advertise tech-editing jobs. Testers can participate without charge, while designers pay per testing or job post, use credits that the pricing page says do not expire, or use a monthly subscription that the page says can be canceled. |
