| 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. | 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. | The tool does not verify label values, convert between metres and yards, identify fibre or yarn diameter, assign a yarn-weight category, predict gauge or fabric, prescribe reserve, guarantee required quantity, check dye-lot supply, score candidates, or approve a substitution. A representative treated specimen and project-specific fabric, care, wear, comfort, supply, and quantity review remain required. |

| 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 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. | The planner performs visible arithmetic only on user-entered project length, reserve, package length, package mass, and price. Its connected source-reviewed guide cites the current Craft Yarn Council category, FAQ, WPI, and hook-and-needle guidance plus ASTM and ISO linear-density sources, and explicitly separates label comparison from substitution approval. |
