| Know before using | 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. | 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 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. | 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. | Knitter or crocheter researching patterns and yarns while keeping notebook records. | 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. | Official about, apps, Goodies, login, and signup pages are public. The useful database, notebook, community, and API root require sign-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 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. | 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. | 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. | 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 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. | 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. | 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. | Not yet reviewed at this level. |
| Source and review | ||||
| What the source establishes | 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. | 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. | 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. | 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. |
