I have a pull-over with a ribbed neckband (already joined at the shoulders) and a separate hood. Instructions simply say, “attach cast on edge of hood where stitches were picked up for neckband”. Can someone recommend a joining technique? I’ll be stitching purl side to purl side, but not edge to edge as the hood cast on edge will join in the “middle” of a piece (where neckband joins sweater body). Whip stitch doesn’t seem strong enough to take the burden of being pulled over the head repeatedly.
