Heritage is a fingering weight blend of superwash merino and nylon that is super-soft yet durable enough to be machine wash and dry. Heritage has become a staple with sock knitters. The superwash merino blocks like a dream and shows off lace shawls with a balance of structure and drape. With so many colors to choose from you will find the perfect shade for socks, accessories, and shawls. 75% Superwash Merino/ 25% Nylon Fingering Weight Yarn.
