| Best for | Checking GOTS certification records | Following a structured classroom introduction to womenswear block development, muslin test fitting, fit correction, and basic flat-pattern manipulation | Translating a seam allowance already stated by a pattern or controlled specification | Building a substitution shortlist for a discontinued or unavailable yarn before checking quantity, availability, and a representative swatch |
| Know before using | A company result is not a blanket approval; confirm the certificate scope, validity, facility, process, product, and transaction documentation for the exact purchase. | This is a classroom textbook with particular womenswear exercises, charts, figures, terminology, units, and drafting methods. It is not a universal body, block, grading, or sizing system; current industry certification; or proof of fit for an individual wearer or product. Some content and examples predate the current review. Verify the intended body data, measurement protocol, ease, material, seam and construction rules, accessibility, current curriculum status, and representative sewn fit independently. | This is a unit-translation reference. It does not select, approve, or change a seam allowance; establish a universal fraction; interpret an unstated cutting or stitching line; or replace the exact pattern version, controlled specification, material and seam evidence, sample, production method, equipment, tolerance, or release authority. | 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. |

| Source and review | ||||
| What the source establishes | The official GOTS search exposes certified entities by country, field of operation, product category, and certification detail, including processing and trading scopes. | CBSE's official publication index links the Class XII Fashion Studies textbook. Its Basic Pattern Development chapter covers body and dress-form measurement, size relationships, patternmaking tools and terms, fit and balance, muslin test fitting, block correction, bodice, sleeve and skirt blocks, seam allowances, grain lines, notches, necklines, collars, and dart manipulation. The stated learning outcomes include developing blocks from charts and body measurements, testing fit, correcting the pattern, and developing simple designs from basic blocks. | NIST states that one inch is exactly 25.4 millimetres, and the SI decimal relationship makes one centimetre equal to 10 millimetres. The tool uses those factors, displays rounded equivalents, exposes the size difference to the nearest 1/16 inch when converting to inches, and preserves valid value, source-unit, and target-unit state in the URL. | 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. |
