| Know before using | 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. | Community members add and quality-control the records, so confirm sizing, measurements, fabric suggestions, format, availability, errata, license, and purchase terms with the designer or publisher. Adding an entry to a stash does not provide the pattern files. Saved searches and private PDF storage are paid Plus features, and a listing or review does not establish pattern accuracy or fit. | The record does not create a production grade, supply universal increments or breakpoints, validate a CAD file or fit population, reproduce licensed standards, or replace qualified anthropometric, pattern, technical-design, fit, quality, accessibility, safety, statistical, and user-research review. | 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. |

| Access scope | Knitter or crocheter researching patterns and yarns while keeping notebook records. | Sewer searching pattern records or organizing patterns, projects, fabric, notions, and private files. | Not yet reviewed at this level. | Knit or crochet tester, designer, sample maker, or tech editor using one role-specific workflow. |
| Before an account | Official about, apps, Goodies, login, and signup pages are public. The useful database, notebook, community, and API root require sign-in. | Browse the pattern database, guide, designers, publications, and public community areas without creating an account. | 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 | 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. | A free account needs no card and supports a stash, wishlist, projects, reviews, and personal organization. | 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 | 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. | Plus adds PDF pattern storage, collections, saved searches, bulk editing, and other workflow features on monthly or annual billing. | 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 | 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. | Cancel through an in-account link. Paid features remain through the current billing cycle, then the account returns to free features. | 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 | 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. | The terms say submitted materials remain yours, but the checked public pages do not explain a full export or how stored PDFs behave after downgrade. Keep originals outside the platform. | 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 | 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. | Threadloop's official guide describes an independent, fully crowdsourced database covering available and out-of-print sewing patterns. Its search supports pattern type, fabric type, age group, body type, cup size, level, format, file features, language, measurements, availability, and other filters; members can also track a stash, wishlist, projects, reviews, and discussions. Current terms state that the free plan requires no card, paid upgrades start billing immediately, cancellation retains paid features through the current cycle, and the account then returns to free features. | The guide cites current ISO body-table, size-designation, and garment-measurement boundaries plus two peer-reviewed studies that tested the relationship between conventional grade rules, anthropometric evidence, and garment fit; it requires product-specific target deltas and validation instead of publishing universal increments. | 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. |
