That's cute! Thinking back to what I read...you might knit the first couple of increase rows flat so you have 12 stitches then switch to circular. I think that was one of the suggestions in the thread where it was talked about. You'd just use the tail to close up the ends of the rows you knit flat.
Cheating is an option. . . . Cheaters never win and winners never cheat, but smart knitters who want to retain an iota of sanity do, cheerfully. ~~Kory Stamper
