Repeat of 22 + 1. Even rows can be worked in knit instead of purl (as was the original from Knittingfool.com). Change colors every 2 rows, or as often or rarely as you'd like. Knittingfool.com reminds us to work the increases and decreases in pattern on the cast off row. I did change the ssk and k2tog at the start and end to better fit the pattern. Rows 1-4 form the pattern.
