I have a similar problem with a few possible answers
I'm knitting a zipped sweater front and I want the pattern to match with multi color yarn. That's how the pants were made. I believe that both pant fronts have to be knit at the same time off the same ball of yarn so the pattern is compatable. My problem is I'm not sure how to bind off on one side and start the other side on each row so that the whole thing doesn't unravel. There has to be a special stitch. Either that or it's knit and then fabric fused and then cut and sewed into pants. Any one have any ideas?
