Quatro is another family of colorways in Cascade's Heritage line. The yarn is made of 4 coordinating colors, twisted together.
You'll like the this yarn knits up, and your feet will like the soft springiness of the yarn. Also great for scarves, shawls, mitts, gloves, cowls and hats.
Machine wash in cool water, lay flat to dry.
1 skein is enough for 1 pair of most socks.
