The project I'm working on is a Feather and Fan scarf with Garter stitch borders. With this pattern, the cast on edge results in a scallop, but not so for the bind off edge. To produce a scallop on both ends of the scarf, I'm knitting the scarf in two lengths and want to join them together invisibly.
I know how to do the Kitchener stitch in both Garter stitch and in Stockinette, but it's the transition from Garter stitch to Stockinette that I can't figure out.
I hope this clarifies.
