This is a really good project for leftover yarn. A friend of mine had made this basic pattern a few years ago and rather than using a solid color like she did, I chose to use a variety of colors. Although it's really, really basic, I always enjoy making things with my friends.
yarn: 5 assorted colors and textures, nothing too bulky. Because I was using odds and ends, I didn't really measure out how much I was using.
needles: size 7 rosewood
Cast on 30 stitches, then work a random pattern in stockinette stitch (try random stripe generator, it's really fun). Continue until piece measures 7 inches, or more if you desire a longer look. My friend Amber made some really fun elbow-length warmers, a good way to spice up 3/4 length sleeves in the winter. Cast off, leaving an 8-inch tail. Fold the completed piece in half. You will begin to stitch the sides together using a darning needle and extra yarn. Use the 8-inch tail to stitch the top 1.5 inches together. Then begin stitching the opposite end. You will stitch 4 inches in toward the middle, leaving a 1.5 thumb hole.
overall: Super easy project, knits up fast, fun to wear. I think if I were to make these again, I would knit in the round.
