I bound off for the bottom of the minisweater today. I did 2x2 ribbing instead of the garter stitch. I tried to find an interesting edging in Knitting On The Edge, but the only ones that really interested me were for the cast on edge (some of the picot edging).
But, I have to say, that I hate binding off on purl stitches. It is just so fiddly, and it is even worse in ribbing because I have to switch back and forth.
