Ruffled Wrist Warmers

After knitting a shirt, I had some black yarn left over and decided to make new wrist warmers. I cast on 33 stitches and knitted in stockingette stitch. I wasn't sure how long to make them, so I added four inches past my wrist, but you can make them however long you want. I added four rows of "ruffles" yarn to the end and sewed up the sides, leaving a space for the thumb hole.
