| Know before using | 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. | 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, and project records can vary in currency and accuracy. Search results, ratings, favorites, and project examples do not establish pattern accuracy, yarn availability, seller reliability, fit, gauge, or project suitability. Confirm current files, errata, license, purchase and refund terms, measurements, yarn details, and shop information with the responsible source. | 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. |

Verify the current in-account help before contributing records. | Not yet reviewed at this level. |
| Saved work and data | 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. | 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 personal notebook can hold projects, stash, tools, and a pattern library, but the checked public pages do not establish a complete export route. Keep source files and critical records locally. | Not yet reviewed at this level. |
| Source and review | ||||
| What the source establishes | 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. | 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 for designers, pattern sources, local yarn stores and yarn brands, and a personal notebook for projects, stash, tools, library items, queues, and favorites. Community members and volunteer editors add and maintain the database records. | 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. |
