Dyed wool yarn in the United States refers to wool fibers that have been processed and colored for use in knitting, crochet, and weaving projects. The dyeing process may occur at different production stages, including fiber, spun yarn, or finished skein, using natural or synthetic dyes. Dyed wool yarn is available in a wide range of colors, from solid shades to variegated and tonal variations. It is produced in multiple weights, such as lace, fingering, worsted, and bulky, to accommodate various patterns and techniques. Fiber characteristics, including warmth, elasticity, and moisture management, remain key factors in project selection.
