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.
