I had fun creating this coffee cozy. It's colorful, light, and fun to carry around on my mug.
Working lengthwise, cast on sts for desired length, allowing 11 sts for each pattern, plus 2 sts. For the coffee cozy, I used size US 6 knitting needles and cast on 33 sts plus 2. I used a combination of 2 yarns to enhance the color.
Row 1: Purl
Row 2 (right side): K2; *K1, slip this st back onto left needle and pass 8 sts on left needle over this sts, (YO) twice, knit first st again, K2; rep from * across.
Row 3: K1; *P2tog, work (K1, K1tbl) in first YO, drop this YO from left needle, work (K1, K1tbl) into remaining YO, P1; rep from * to last st, K1.
Row 4: Knit
Row 5: Knit
Row 6: Knit
Row 7: Add button hole as described in my garter Garter Cozy blog entry
Continue to knit all rows until you've reached desired length. BO. Attach button of choice.
