| Best for | Auditing inherited grade rules or controlling a new multi-size pattern release from approved targets through sample evidence | Broad pattern, yarn, and project research | Turning an ambiguous POM name, code, or diagram into a reproducible method before setting targets, tolerances, or inspection decisions |
| Know before using | 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. | 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 reproduce licensed ISO measurement drawings, supply universal POM codes or targets, approve an internal method, prove measurement capability or product fit, or replace qualified technical-design, pattern, fit, quality, metrology, safety, and regulatory review. |

| Access scope | Not yet reviewed at this level. | Knitter or crocheter researching patterns and yarns while keeping notebook records. | Not yet reviewed at this level. |
| Before an account | Not yet reviewed at this level. | Official about, login, and signup pages are public, but the useful database, notebook, and community route requires sign-in. | Not yet reviewed at this level. |
| Free-account boundary | Not yet reviewed at this level. | A free account requires a valid email signup link and enables the database, notebook, directories, groups, and forums. | Not yet reviewed at this level. |
| Payment boundary | Not yet reviewed at this level. | 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. |
| Cancellation or exit | Not yet reviewed at this level. | 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. |
| Saved work and data | Not yet reviewed at this level. | 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 | 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. | 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 current ISO garment-measurement, body-measurement, and textile-conditioning standards plus NIST measurement-process guidance for repeatability and reproducibility; it requires organization-specific codes, added points, targets, and tolerances to remain explicitly controlled. |
