Know before usingAn 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.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.The workflow is not a contract or quality certification; local legal duties and technical review may still apply.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.

Source and review
What the source establishesRavelry'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.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.The linked tool or guide is maintained inside Stitch Authority and was checked against its current public interface.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.
