| Best for | Investigating an unknown textile without using flame, smoke, odor, or residue as composition, flammability, care, safety, or compliance proof | Integrated pattern, marker, and 3D production workflows | Free editorial knitting patterns and techniques |
| Know before using | The record does not identify a submitted textile, provide a home burn procedure, turn an observation into a fibre or blend result, choose a laboratory method, establish flammability or market compliance, validate a care instruction, or replace qualified laboratory, textile, conservation, safety, compliance, and legal review. | 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. | Free access does not grant commercial reproduction or sale rights; uses beyond one personal copy must be resolved with the designer or author. Knitty says it tries to avoid errors but disclaims responsibility for pattern and technique inaccuracies. Check the live page for corrections, verify gauge and measurements, and confirm permission before any commercial use. |

| What the source establishes | The guide cites current AATCC qualitative and quantitative fibre-analysis methods, the published ISO 1833-1 quantitative-analysis principles, ASTM's withdrawn D276 status and reinstatement work item, current FTC U.S. textile-label guidance, and current CPSC clothing-textile flammability guidance. | 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. | Knitty currently publishes web-only editorial issues containing original knitting and crochet patterns and articles. Its legal page states that patterns are free for one person's personal use, identifies each designer or author as the copyright holder, and explains that verified pattern corrections are posted in bright pink on the pattern page. |
