| Know before using | The MRSL controls manufacturing inputs within its stated scope. It does not by itself prove a facility's chemical inventory, implementation, worker protection, emissions, wastewater performance, formulation conformance, or finished-product compliance. Verify the current version, law, brand program, safety rules, chemical-product certificates and status, facility records, 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. | 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. | A foundational library, not yet an exhaustive stitch encyclopedia. |

| What the source establishes | 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's help centre identifies version 3.1 as the current official MRSL and distinguishes it from restrictions measured in finished products. | 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. | 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 linked tool or guide is maintained inside Stitch Authority and was checked against its current public interface. |
