| Primary job | Find patterns & fit | Source production | Learn techniques | Find patterns & fit |
| Area | Patterns & fit | Production | Yarn | Patterns & fit |
| Best for | Auditing inherited grade rules or controlling a new multi-size pattern release from approved targets through sample evidence | Understanding what a tech pack must control before using a template or releasing work | Checking which U.S. alias the current Craft Yarn Council table gives a known metric package size before confirming project gauge | Custom-fit home sewing patterns |
| 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. | 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. | 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 generated pattern is not independent fit evidence or a production-ready graded block. The result still depends on accurate measurements, the selected design and options, ease assumptions, fabric behavior, construction, and representative test garments. An account stores saved patterns and measurement sets, so review the platform's privacy terms before retaining personal measurements. |

| 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 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. | 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. | FreeSewing's official documentation says the browser editor drafts a selected design in real time from a measurement set rather than scaling or grading a standard-size pattern. Users can adjust design options and export the generated result, including as PDF; saving the pattern to an account is optional and is used to revisit it later. |
