# Stitch Authority resource comparison Generated: 2026-08-01T11:51:47.459Z 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: 2026-07-30 - Next review due: 2026-10-28 ### 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 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. ### Know before using 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. ## 2. 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. ## 3. Optitex 2D/3D Pattern Design Permanent record: Source page: - Primary job: Find patterns & fit - Area: Patterns & fit - For: Apparel brands - Location or jurisdiction: Global - Access: Quote-based - Format: Software - Source type: First-party platform - Linked page reviewed: 2026-07-21 - Next review due: 2027-01-17 ### Best for Integrated pattern, marker, and 3D production workflows ### What the source establishes Optitex's current page describes 2D pattern creation, grading, verification, Tech Pack Essentials, marker creation and nesting, cut and plot output, 3D virtual samples, fabric simulation, colour and print placement, tension maps, and avatar editing. Its support page lists native and standard CAD interchange routes and states that Optitex does not support macOS. ### Know before using Pricing is not public, modules and system requirements must be confirmed, and macOS is not supported. Vendor accuracy and fit language does not prove results for an actual product. Pilot native and exchanged files with the receiving supplier, calibrated materials, approved blocks and grade rules, marker and output devices, tech-pack fields, training, version control, and risk-appropriate physical fit and production checks. ## 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.
