The Zipper Neck is worked from the top down. The collar is worked in rib, then folded double and knitted together. After this, the shoulders are worked with increases on both RS and WS rows and short rows to shape the neckline. Then the front and back are worked. Finally, a facing for the zipper is worked from resting stitches, so the zipper, after being sewn in, also looks presentable from the WS. The zipper is sewn in between the two layers of knitting – either by hand or on a sewing machine.
