From the book:

"These striped slippers are as soft and comfy as a pair of heavy socks, and they’re knitted the same way.  For a variation on the pictured slippers, knit plain-color heels and toes in one of the contrasting yarns, or turn them into super-fuzzy slippers by holding a strand of brushed mohair with the worsted-weight yarn."



Uses 5 colors of yarn as written.
