Always bind off stitches at the beginning of the row, otherwise you do have that stitch in the wrong place. From what you put in the previous post, I understand that you need to work across. That would tell me to the stitch holder, probably. then connect the new yarn at the neck edge, bind off three
on that side of the neck.
Are you working two sides seperately? The fact that you had to connect a new yarn says, yes. Yes?
I hope this makes some sense. If not, maybe you can explain the pattern a little more from the 'neck edge' section.
