I stumbled onto a method that works. I knit about 4 rows of reverse stockinette to start and kept 5 sts on each end in reverse St st also. The rev St part rolls a little, but since it's only an inch, it's not nearly as bad. Also, instead of slipping the first st, I'm slipping the last st on each row and that looks really well. When I slip the first st, the loops wind up a lot bigger than if I just knit or purl as usual so I don't do that. Slipping the last st gives you the same kind of edge, but for me the stitches aren't so loopy.
