| Know before using | Patternmaking knowledge, controlled measurement files, production conventions, and sewn fit testing are still required. The software does not validate body measurements, ease, balance, grading rules, fabric behavior, construction, or product fit. The project currently labels its user wiki manual as needing updates, so confirm current commands and file behavior against the installed release and active support channels. | 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. | 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. | 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. |

| Access scope | Not yet reviewed at this level. | Maker comparing a replacement for a named yarn before buying. | Knit or crochet tester, designer, sample maker, or tech editor using one role-specific workflow. | Not yet reviewed at this level. |
| Before an account | Not yet reviewed at this level. | Search a named yarn, inspect suggested substitutes, and filter by fibre and approximate price band without creating an account. | Browse public open testing calls and the provider's feature and pricing pages without signing in. | Not yet reviewed at this level. |
| Free-account boundary | Not yet reviewed at this level. | The checked core substitution route does not require an account, and the FAQ does not offer user-entered yarn records. | A free signup lets people look around, and testers participate without a platform charge. Designers and tech editors face different role boundaries. | Not yet reviewed at this level. |
| Payment boundary | Not yet reviewed at this level. | 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. | 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. | Not yet reviewed at this level. |
| Cancellation or exit | Not yet reviewed at this level. | There is no account or recurring plan to cancel for the core route. The newsletter has a separate unsubscribe link. | 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. | Not yet reviewed at this level. |
| Saved work and data | Not yet reviewed at this level. | 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. | Designers can download pattern-test feedback as CSV or XLSX. The checked pages do not establish a full account export or deletion route. | Not yet reviewed at this level. |
| Source and review | ||||
| What the source establishes | The maintained Seamly2D repository identifies the application as GPLv3+ open-source patternmaking software for Windows, macOS, and Linux. It reads multi-size measurement files for standardized sizes and individual measurement files for custom-fit work, publishes downloadable builds and releases, and links an active website and user forum. | 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. | 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. | 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. |
