| Best for | Documenting a bounded sample-to-area yarn calculation when the equivalent area is already known and genuinely comparable with the sample | Building a substitution shortlist for a discontinued or unavailable yarn before checking quantity, availability, and a representative swatch | Understanding what a tech pack must control before using a template or releasing work | Custom-fit home sewing patterns |
| Know before using | The worksheet does not establish that a sample represents a project, derive the area of shaped pieces, account for construction or openings, prescribe reserve, supply typical project quantities, round to packages, verify label values, guarantee required quantity, check dye-lot supply, or replace a tested pattern amount. Yarn, tool, maker, strand count, stitch or texture, density, treatment, finishing, planned area, and supply decisions remain project-specific. | A suggested match is a data-based shortlist, not proof that the yarn suits the pattern or maker. Records can be incomplete or wrong, price bands are approximate, availability varies by country and seller, and shade-level matching is unavailable. YarnSub says affiliate status does not change suggestions, but equally rated matches are ordered by brand popularity. Confirm required gauge, total length, fibre behavior, construction, care, colour, dye lot, accessibility, price, availability, and seller terms, then make and assess a representative swatch before committing. | 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. | 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. |

| Source and review | ||||
| What the source establishes | The worksheet performs visible proportional arithmetic on user-entered sample dimensions, sample yarn length or weight-derived length, equivalent area, and optional reserve. Craft Yarn Council pattern-writing guidance says yarn amounts and package counts should be recorded in instructions, and its consumer guidance ties project instructions to a stated yarn amount and representative gauge; those sources do not establish a universal sample-to-area method, project range, or reserve. NIST defines 1 yard as exactly 0.9144 metre for the secondary unit display. | YarnSub's official FAQ says its matching software compares gauge, texture, yarn weight and density, fibre content, and fibre qualities such as drape and softness. Discontinued yarns remain searchable as starting points but are excluded from suggestions. Result filters can exclude animal, animal-derived, synthetic, or plant fibre groups and use a subjective $ to $$$$$ price indicator. The site does not accept user-entered yarn details, individual shade cards, or expose an API. Each yarn page provides a data-issue route. | The guide cites published ISO sources for documented-information, garment-measurement, stitch, and seam boundaries plus current U.S. FTC textile and care-labeling guidance; it discloses that ISO 10013:2021's 2026 systematic review is at close-of-review stage and separates every cited authority from product-specific technical and market decisions. | 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. |
