A favorite amongst sock knitters, Opal sock yarn is both soft & durable. Opal is located at the foot of Hohenzollern Castle in the knitting town of Hechingen in Baden-Württemberg, Germany. With a focus on quality & sustainability, each unique collection of self-patterning colorways make sock knitting fun & interesting. Of course, Opal yarns are also fabulous for shawls, wraps, hats/scarves, & even cute baby garments!
