Is there a link to the pattern or at least a picture of the finished sweater?
sometimes the fronts of a sweater, you bind off the shoulders and some stitches at the neck edge continue around the neck to the middle of the back/neck (the other side continuing around the other side of the neck) and the 2 meet in the center of the back. These form sort of a collar, maybe a shaw collar that folds down. Sounds like you're doing something like that.
Mirl56 at Ravelry, too.
