| Know before using | The interface and plan description do not prove tester reach, completion, feedback quality, fit validity, export quality, uptime, support, or suitability for an established release process. Measurements and photos can be sensitive personal data. Run a non-critical pilot, review the current privacy and service terms, define consent and photo rights, test exports and deletion, and keep pattern approval and release responsibility with the designer. | 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 workflow is not a contract or quality certification; local legal duties and technical review may still apply. | An account is required and community, publisher, designer, shop, yarn, project, and connected-app records can vary in currency and accuracy. The checked public pages do not establish API credential eligibility, current endpoints, scopes, rate limits, support, app quality, or a complete account export. Search results, ratings, favorites, and project examples do not establish pattern accuracy, yarn availability, seller reliability, fit, gauge, or project suitability. Confirm current developer terms, files, errata, license, purchase and refund terms, measurements, yarn details, and shop information with the responsible source. |

| 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. | Not yet reviewed at this level. | Official about, apps, Goodies, login, and signup pages are public. The useful database, notebook, community, and API root require sign-in. |
| 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. | Not yet reviewed at this level. | A free account requires a valid email signup link and enables the database, notebook, directories, groups, and forums. The public Goodies page sends developers to an account-gated API group; it does not establish current credential eligibility, scopes, endpoints, rate limits, or support. |
| 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. | Not yet reviewed at this level. | The core platform account is free. Individual patterns and other marketplace items may have separate provider-set prices; those purchases are not a user subscription. |
| 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. | Not yet reviewed at this level. | The checked public about, login, and signup pages do not establish cancellation, deletion, or post-exit access. Verify the current in-account help before contributing records. |
| 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. | Not yet reviewed at this level. | The Goodies page documents a stash spreadsheet and a Project Progress API JSON route, but it says exports are limited and does not establish one complete account export. Keep source files and critical records locally. |
| Source and review | ||||
| What the source establishes | Pattern Testers currently offers application intake, tester selection, feedback, photos, approvals, issue tracking, revisions, a reusable tester directory, and release deadlines. The public pricing page shows a limited free plan and paid Pro and Business tiers. Its June 2026 privacy policy lists names, email addresses, measurements, photos, feedback, application history, and assignments among the data processed. | 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 linked tool or guide is maintained inside Stitch Authority and was checked against its current public interface. | Ravelry's official description identifies a user-driven database of knitting and crochet patterns and yarns, searchable directories, and a personal notebook. Community members and volunteer editors maintain database records. The current official Goodies page exposes an account-gated developer API route, a limited Project Progress API JSON export, and a stash spreadsheet; the official apps directory lists third-party apps that connect to Ravelry. |
