This is a fairly simple, but warm pattern for slippers. It uses two strands of yarn OR 1 strand of bulky yarn. I used an N hook for this and I hope I've adjusted the pattern this time to take into account the guage I crochet. These should fit an adult foot. They're warm and comfy too, I made myself a pair!
