| Best for | Finding the current CYC hook and needle aliases that share one known nominal metric diameter before confirming project gauge | Structured wool education | Cross-referencing sewing patterns, materials, and member projects | Auditing inherited grade rules or controlling a new multi-size pattern release from approved targets through sample evidence |
| Know before using | A shared nominal diameter does not make a knitting needle and crochet hook interchangeable or predict equal gauge or fabric. The reference is not a physical measurement, manufacturer inspection, UK or Canadian conversion, steel-hook chart, tool recommendation, yarn assignment, or project approval. | 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. | Textillia is community-contributed and now runs with minimal maintenance, so record freshness, coverage, moderation speed, and continued availability require direct inspection. It does not sell the indexed patterns or materials. Confirm pattern files, sizing, measurements, availability, licence, errata, fabric details, and seller terms with the responsible designer, publisher, or manufacturer. Account deletion permanently removes uploaded projects, and the checked pages do not establish a complete export route. | 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. |

| What the source establishes | Rechecked July 28, 2026. The lookup reproduces the current public Craft Yarn Council metric and U.S. alias rows, aligns hooks and needles only when their nominal millimetre value matches, and leaves missing rows or aliases unfilled. | 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. | Textillia's current about page describes an independent, centralized, crowdsourced database that cross-references sewing patterns, materials, resources, projects, designers, companies, and shops. Its FAQ says the site does not sell patterns or fabric, logged-in members can add records, full database access uses a free account, and paid memberships will not launch. A February 2026 notice says the dissolved company will continue the site as a donation-supported hobby project with minimal maintenance and reduced active development. | 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. |
