Frequently Asked Questions

How much yarn for a blanket? +

A baby blanket needs ~400–700m in worsted weight. An adult lap blanket needs ~800–1200m. A full bed blanket needs ~1500–2500m. Thicker yarn = fewer metres needed but each skein covers less.

How many skeins of yarn do I need? +

Divide total metres needed (including a 15% buffer) by metres per skein. Always round up to the nearest whole skein. Buy all skeins from the same dye lot.

What does yarn weight mean? +

Yarn weight refers to the thickness: Lace (thinnest), Fingering, DK, Worsted, Aran, Bulky, Super Bulky, Jumbo (thickest). Thicker yarn produces thicker fabric, knits faster, but uses more grams per metre.
