| Know before using | 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. | The record does not create product specifications, prove fit or manufacturability, select materials or construction settings, establish legal compliance, reproduce licensed standards, or replace qualified technical, production, quality, testing, sourcing, logistics, safety, compliance, 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. | 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. |

| 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 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 guide cites published ISO documented-information, garment-measurement, stitch, and seam sources plus current U.S. FTC textile and care-labeling guidance; it discloses ISO 10013:2021's current review stage, and its working record makes organization-specific requirements, suppliers, evidence, issues, and approvals explicit. | 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 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. |
