It's beautiful.
Those are my kind of scrappies---they use up scraps and you don't have to go out and buy more fabric. A lot of scrap quilts have a main 'pull-it-all-together 'fabric so sometimes you have to go out and buy that fabric and you use less scraps. Am I making sense?
Can't help on the binding/backing---maybe black for binding ....or a black border and then a scrappy binding.
