Source and review
What the source establishesThe 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 Handweavers Guild of America's current resources page links a searchable affiliate-guild directory, a paid professional-member directory and fiber-art resource guide, book reviews, a public event calendar, scholarships, a quarterly member magazine, and program and store information for weaving, spinning, dyeing, and related fiber arts.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 official GOTS search exposes certified entities by country, field of operation, product category, and certification detail, including processing and trading scopes.
