I like a scrappy binding but unless you were crazy on top of it it just wouldn't look right here. I've found the more seams I try to put in my binding no matter how hard I work at it, the more it tries to "veer" off straight.
What about a batik that has a rainbow of the colors from the quilt in it? That's the best of both worlds and it wont show dirt the way black would or show wear the way some dark colors might.
