This pattern uses the following skills: Chain Stitch (ch) Single Crochet (sc) Double Crochet (dc) Cluster Stitch (cl) Yarn: I used Big Twist Chunky Yarn (available at Joann) in Raspberry, Cloud White and Chunky Black. These are Bulky 5 weight yarns. Any yarn in this size and color scheme will work. These are 195 yards each, and I used less than 1 skein of each. This pattern uses a color changing technique to make the crisp polka dots.
