This pattern is for making a pillow that exhibits either

(1) a pretty pattern.
(2) all symmetries of a square.

You will need 2 colors, and using the suggested yarn/needles, 1 skein each of yarn should be sufficient (more than sufficient for the contrast color).

Suggested materials for the pattern: yarn, size 8 circular needles, size 8 double pointed needles, blunt needle for kitchener stitch/sewing, and possibly a crochet hook for provisional cast on.
