You can also pull yarn from the other end of the skein or ball you're using rather than cut some off and hope you got enough but not too much. Or knit one side then cut it and start the other side. You'll end up with the same number of ends I think. Good luck on your adventure. I'll be interested in updates.
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
