| 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. | The MRSL controls manufacturing inputs within its stated scope. One formulation status or self-generated facility inventory report does not by itself prove a complete or externally verified chemical inventory, actual order recipe, implementation, worker protection, emissions, wastewater performance, or finished-product compliance. Verify the current version, law, brand program, safety rules, formulation identity and status, complete facility and order records, inventory-verification state, and finished-product RSL and testing requirements. | 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. | The workflow is not a contract or quality certification; local legal duties and technical review may still apply. |

| 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. | ZDHC's current scope defines the MRSL as restrictions on intentional use of listed substances in commercial chemical formulations for textile, leather, rubber, foam, adhesive, and trim processing. Covered inputs include cleaners, dyes, auxiliaries, coatings, finishing agents, maintenance, wastewater-treatment, sanitation, and pest-control chemicals. ZDHC identifies version 3.1 as the current official MRSL, distinguishes formulation conformance from finished-product restrictions, and states that an ordinary Performance InCheck facility inventory is self-generated rather than externally verified. | 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. | The linked tool or guide is maintained inside Stitch Authority and was checked against its current public interface. |
