| Best for | Checking which U.S. alias the current Craft Yarn Council table gives a known metric package size before confirming project gauge | Structured wool education | Planning the current CPSC certificate-data handoff for regulated imports with the importer, finished-product certifier, customs broker, and entry records | Documenting how a pattern-based fabric quantity becomes an order length |
| Know before using | The reference is not a dimensional measurement, manufacturer inspection, UK or Canadian conversion, steel-hook chart, tool recommendation, yarn assignment, gauge result, or proof that a proposed tool will produce the required fabric. | 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 portal does not decide whether a product requires certification, identify the correct rules or certificate data, classify an entry, replace the current 16 CFR part 1110 text, or reconcile a filing to an actual shipment. Effective dates and workflows differ by entry route; use current CPSC, CBP, customs, product-safety, and legal review. | The planner adds and rounds user-entered lengths; it does not create a cutting layout, infer shrinkage or matching allowances, compensate for a width change, establish usable width, or prove that the order quantity is sufficient. |

| What the source establishes | The lookup reproduces the current public Craft Yarn Council metric and U.S. alias rows and follows the Council's warning that company letter and number labels vary; blank aliases remain blank instead of being inferred. | 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. | CPSC operates the eFiling portal with role-specific importer, broker, applicability, Product Registry, regulated-product, laboratory, ACE, FAQ, video, and document-library routes. The certificate final rule took effect July 8, 2026 for covered non-FTZ products, with separate timing for covered FTZ entries. | NIST defines 1 yard as exactly 0.9144 metre. Sewing & Craft Alliance guidance ties an applicable cutting layout to the exact view, size, fabric width, and nap condition and recommends layout work when listed conditions do not fit the project. |
