| Best for | Finding member reports about a named sewing pattern | Broad pattern, yarn, and project research | Planning the current CPSC certificate-data handoff for regulated imports with the importer, finished-product certifier, customs broker, and entry records | Searching current and out-of-print sewing patterns |
| Know before using | PatternReview combines community reports, membership, education, advertising, and retail, so it is not a neutral or complete pattern index. Reviews are individual experiences rather than standardized fit tests. Confirm the exact pattern version, size range, measurements, fabric, format, errata, licence, seller terms, and current availability with the designer or publisher. Paid catalogue and search features do not establish an export route or continued access after membership ends. | 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. | The portal does not decide whether a product requires certification, identify the correct rules or certificate data, classify an entry, replace the current 16 CFR part 1110 text, or reconcile a filing to an actual shipment. Effective dates and workflows differ by entry route; use current CPSC, CBP, customs, product-safety, and legal review. | 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. |

| Access scope | Sewer reading community pattern reports, participating in discussions, or keeping a personal pattern catalogue and wishlist. | Knitter or crocheter researching patterns and yarns while keeping notebook records. | Not yet reviewed at this level. | Sewer searching pattern records or organizing patterns, projects, fabric, notions, and private files. |
| Before an account | Browse recent pattern reviews, the review gallery, shop, classes, blog, and public help pages 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. | Browse the pattern database, guide, designers, publications, and public community areas without creating an account. |
| Free-account boundary | Free membership requires email activation. The account FAQ says most participation and member-only areas require sign-in. | 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. | A free account needs no card and supports a stash, wishlist, projects, reviews, and personal organization. |
| Payment boundary | Friends of PR costs $34.95 per year and adds advanced search, a personal pattern catalogue and wishlist, bookmarks, classifieds, discounts, and other features. | 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. | Plus adds PDF pattern storage, collections, saved searches, bulk editing, and other workflow features on monthly or annual billing. |
| Cancellation or exit | Friends of PR recurs on its plan cycle. The account FAQ says an advance email includes cancellation instructions and also publishes an email cancellation route. | 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. | Cancel through an in-account link. Paid features remain through the current billing cycle, then the account returns to free features. |
| Saved work and data | Paid tools can hold a pattern catalogue, wishlist, bookmarks, and photos, but the checked pages do not establish a complete export or post-membership retention route. Keep critical records elsewhere. | 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. | 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. |
| Source and review | ||||
| What the source establishes | PatternReview's current site exposes recent pattern, sewing-machine, and store reviews, forums, contests, classes, classifieds, a pattern shop, and a searchable review gallery. Its account FAQ says most participation requires a free activated account. Friends of PR adds advanced search, a personal pattern catalogue and wishlist, bookmarks, classifieds, a photo album, discounts, and other features through a recurring paid membership with a published email cancellation 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. | CPSC operates the eFiling portal with role-specific importer, broker, applicability, Product Registry, regulated-product, laboratory, ACE, FAQ, video, and document-library routes. The certificate final rule took effect July 8, 2026 for covered non-FTZ products, with separate timing for covered FTZ entries. | 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. |
