Hi, welcome to KH. I think your only fix is to rip it back to where you joined to work in the round and reknit it. I'm sorry I can't give you an answer you'll like better. Maybe someone else will know how to work it out another way.
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
