It's another fantastic yarn from Mrs. Crosby - Steamer Trunk! Steamer Trunk is a worsted weight, 4-ply yarn in glorious hand-dyed, tonal hues. This yarn has fantastic stitch definition, and knits up beautifully into almost anything you can imagine: sweaters, hats, cowls, cabled projects or even cozy, warm blankets. Although the phrase "work horse yarn" would apply here, it doesn't express the softness and beauty of this yarn. Steamer Trunk is machine washable, too!
