I agree to black sashing with cornerstones. It will give it a stained glass look and accent all of the colors. You could also add a border that would drop from the ends and edges of the existing quilt and would incorporate duplicates of some of the blocks that you liked or colors that you want to accent more.This would also make it wider and longer.
