| Best for | Finding or checking paper-based packaging and hangtag suppliers with PEFC chain-of-custody scope | Custom-fit home sewing patterns | Searching current and out-of-print sewing patterns | Auditing inherited grade rules or controlling a new multi-size pattern release from approved targets through sample evidence |
| Know before using | A chain-of-custody record applies only to the named organization and scope; verify the exact product claim, current status, supplier role, artwork approval, and transaction documentation for each order. | A generated pattern is not independent fit evidence or a production-ready graded block. The result still depends on accurate measurements, the selected design and options, ease assumptions, fabric behavior, construction, and representative test garments. An account stores saved patterns and measurement sets, so review the platform's privacy terms before retaining personal measurements. | 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. | 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. |

| What the source establishes | PEFC describes the database as a current discovery and verification route for certified organizations, certificate validity, countries, product scope, sourcing, and due diligence. | FreeSewing's official documentation says the browser editor drafts a selected design in real time from a measurement set rather than scaling or grading a standard-size pattern. Users can adjust design options and export the generated result, including as PDF; saving the pattern to an account is optional and is used to revisit it later. | 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. | 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. |
