Weeks Dye Works Crewel Yarn is a 1-ply wool in 30 yard skeins. In addition to crewelwork, embroidery, and plastic canvas projects, this soft, pliable wool is also appealing to knitters and crocheters in place of fingering weight yarns for their projects. It's especially useful for patterns that call for some additional hand or machine stitching, such as in stuffed animals or toys, because the wool skeins can color-match with Weeks Dye Works embroidery floss.
