| Know before using | 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. | A company result is not a blanket approval; confirm the certificate scope, validity, facility, process, product, and transaction documentation for the exact purchase. | Repair Cafés are volunteer events rather than guaranteed commercial services, and each location sets its schedule, item scope, expertise, accessibility, parts policy, and capacity; confirm that clothing or textile help is available before traveling and expect to participate in the repair. | This is Woolmark-operated education focused on wool, not a neutral comparison of all fibres or processing systems. A completion badge records coursework, not independent proof of production competence, product performance, environmental impact, or compliance. Confirm technical values and local requirements against current standards before production use. |

| What the source establishes | 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. | The official GOTS search exposes certified entities by country, field of operation, product category, and certification detail, including processing and trading scopes. | The foundation's current public search reports thousands of registered Repair Cafés across dozens of countries, and its organizer manual includes clothing stations with sewing machines, hand tools, zips, buttons, patches, elastic, darning supplies, and wool-repair equipment. | The current Woolmark Learning Centre library publishes free account-based coursework with module counts, completion times, progress tracking, knowledge checks, and supporting resources. Its wool programs cover fibre science, raw-wool and yarn processing, dyeing and finishing, woven textiles, knitwear, product quality, and wastewater management for learners and facilitators. |
