Forgive me for saying I don't think the sawtooth or pieced border does your beautiful quilt justice. Personally, I would remove it, keep the black print border and the narrow burgundy one, and replace the narrow green border with a wider green one, say 4 or 5 inches. And then bind, perhaps, with the black rose print. The center of your quilt is so striking, that the borders should complete and complement it, not distract from it. Just my opinion, of course.
