| Best for | Checking which U.S. alias the current Craft Yarn Council table gives a known metric package size before confirming project gauge | Individual and team 3D garment prototyping | Coordinating an independent sewing-pattern test | Understanding what a tech pack must control before using a template or releasing work |
| 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. | A virtual sample or coloured fit map is not proof of physical fit, comfort, construction quality, manufacturability, or graded-size approval. Results depend on pattern geometry, sewing, avatar measurements and pose, fabric physical-property data, trims, mesh, and simulation settings. Current releases have substantial hardware and learning requirements; validate representative fabrics, bodies, movements, and sewn samples physically. | 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. | An orientation rather than a completed product record; it does not supply a universal format, licensed standard content, measurements, tolerances, construction settings, labels, approvals, compliance conclusion, or product-release authority. |

| 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. | CLO's current product and support documentation covers linked 2D pattern work and 3D garment simulation on avatars, grading review by size, fabric and garment visualization, fit maps for stress, strain, pressure, and tightness, and rendering and presentation output. Current system requirements publish separate Windows and Apple Silicon baselines and higher recommendations for complex simulation and rendering. | 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 guide cites current ISO sources for documented-information, garment-measurement, stitch, and seam boundaries plus current U.S. FTC textile and care-labeling guidance; it explicitly separates those authorities from product-specific technical and market decisions. |
