# Stitch Authority resource comparison Generated: 2026-07-24T18:25:11.029Z Comparison: This file preserves the published decision metadata for the selected routes. It is not a recommendation, provider approval, compliance decision, or record of project-specific due diligence. ## 1. ZDHC Manufacturing Restricted Substances List Permanent record: Source page: - Primary job: Check standards - Area: Standards - For: Apparel brands - Location or jurisdiction: Global - Access: Open access - Format: Reference - Source type: Industry organization - Linked page reviewed: 2026-07-21 - Next review due: 2026-10-19 ### Best for Chemical-input controls during manufacturing ### 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. ### 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. ## 2. YarnSub Permanent record: Source page: - Primary job: Choose materials - Area: Yarn - For: Makers - Location or jurisdiction: Global - Access: Open access - Format: Reference - Source type: First-party platform - Linked page reviewed: 2026-07-21 - Next review due: 2027-01-17 ### Best for Replacing a discontinued or unavailable yarn ### What the source establishes YarnSub's official FAQ says its matching software compares gauge, texture, yarn weight and density, fibre content, and fibre qualities such as drape and softness. Discontinued yarns remain searchable as starting points but are excluded from suggested replacements, and each yarn page provides a route to report source-data problems. ### Know before using A suggested match is a data-based shortlist, not proof that the yarn suits the pattern or maker. Yarn records can be incomplete or wrong, prices and availability vary by market, and the site uses affiliate links. Confirm the required gauge, total length, fibre behavior, construction, care, color, dye lot, accessibility, and seller terms, then make and assess a representative swatch before committing. ## 3. India Basic Pattern Development Textbook Permanent record: Source page: - Primary job: Find patterns & fit - Area: Patterns & fit - For: Both - Location or jurisdiction: India ยท South Asia - Access: Free download - Format: Reference - Source type: Government guidance - Linked page reviewed: 2026-07-16 - Next review due: 2026-10-14 ### Best for Following a structured classroom introduction to womenswear block development, muslin test fitting, fit correction, and basic flat-pattern manipulation ### What the source establishes CBSE's official publication index links the Class XII Fashion Studies textbook. Its Basic Pattern Development chapter covers body and dress-form measurement, size relationships, patternmaking tools and terms, fit and balance, muslin test fitting, block correction, bodice, sleeve and skirt blocks, seam allowances, grain lines, notches, necklines, collars, and dart manipulation. The stated learning outcomes include developing blocks from charts and body measurements, testing fit, correcting the pattern, and developing simple designs from basic blocks. ### Know before using This is a classroom textbook with particular womenswear exercises, charts, figures, terminology, units, and drafting methods. It is not a universal body, block, grading, or sizing system; current industry certification; or proof of fit for an individual wearer or product. Some content and examples predate the current review. Verify the intended body data, measurement protocol, ease, material, seam and construction rules, accessibility, current curriculum status, and representative sewn fit independently. ## Next checks 1. Remove any route whose audience, jurisdiction, access, or scope does not match the job. 2. Open the permanent record and source page for every remaining route. 3. Recheck facts that can change after the listed review date. 4. Verify project-specific capability, terms, test evidence, and legal requirements with the responsible source or provider. 5. Record the reason for the final choice outside Stitch Authority.
