Tahki Yarns Tucson blends wool and cotton together in a thick-to-thin worsted weight yarn. A single-ply strand of cotton is wrapped around a single-ply wool core. This construction and the two fibers taking dye differently creates a marled appearance that lends interest to the finished fabric. Tucson is very soft, and a great choice for between-seasons accessories, children's garments, and sweaters.
