I agree that you might want to remake the piece with slipped edges as you seem to have a variety of things happening. Looks like some K sts, a P st in a couple instances. The actual patt appears to have a pseudo-decorative edge treatment but that's not in the instructions.
If you opt for slipped sel st, you'd best add 2 add'l sts (to however many you cast on): Slip 1st st, K2, P2, end with K1. Rep this row. This would give you a nice cabled edge.
