The Craft Yarn Council's Standards for Yarn Weight

The Craft Yarn Council's Standards for Yarn Weight categorize yarns based on thickness, helping crafters select appropriate materials for their projects. They range from fine, delicate fibers like lace weight, to bulky yarns suitable for warmer, heavier items. Each category defines typical fiber thickness and recommended needle or hook sizes, ensuring consistent results and proper gauge. This standardized system simplifies choosing yarns and ensures projects turn out as intended, regardless of brand or origin, by providing a common reference for yarn dimensions and recommended tools.
