What about taking all those scraps for a scrappy crazy quilt style border? Or one massive large postage stamp border?
One thing I am planning to do ..... as many postage stamp blocks it takes, to show a piece of every fabric I use in the quilt! I've done this before in other quilts, as a reference piece where I can show someone .... see all these QST all these fabrics were used (or whatever I choose to make them into). I make sure they are all side by side and "fit" with the pattern. If not a lot of fabrics, I will use some of each to frame up the label of the quilt.
