Know before usingThe 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 interface and plan description do not prove tester reach, completion, feedback quality, fit validity, export quality, uptime, support, or suitability for an established release process. Measurements and photos can be sensitive personal data. Run a non-critical pilot, review the current privacy and service terms, define consent and photo rights, test exports and deletion, and keep pattern approval and release responsibility with the designer.Coverage reflects affiliated guilds, submitted events, and participating professionals rather than every regional option. HGA states that its paid professional listings are supplied and updated by the professional and are not HGA endorsements. Confirm current contact details, teaching format, accessibility, price, skill level, and safeguarding or insurance needs directly.

Source and review
What the source establishesZDHC'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.Pattern Testers currently offers application intake, tester selection, feedback, photos, approvals, issue tracking, revisions, a reusable tester directory, and release deadlines. The public pricing page shows a limited free plan and paid Pro and Business tiers. Its June 2026 privacy policy lists names, email addresses, measurements, photos, feedback, application history, and assignments among the data processed.The Handweavers Guild of America's current resources page links a searchable affiliate-guild directory, a paid professional-member directory and fiber-art resource guide, book reviews, a public event calendar, scholarships, a quarterly member magazine, and program and store information for weaving, spinning, dyeing, and related fiber arts.
