Uses two strands of yarn held together.
Requires double pointed needles or circulars.
Pattern starts with at the slipper heel. Pick up along the heel sides (this is where you need DPNs/circs), work in garter stitch flat for a while, then ribbing in the round. Decrease for the toes.

Pattern also calls for making crocheted eyes using small scraps of black, white, and red yarns.
