| Know before using | 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. | A foundational library, not yet an exhaustive stitch encyclopedia. | 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. | 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 | 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 linked tool or guide is maintained inside Stitch Authority and was checked against its current public interface. | 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 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. |
