Those scraps are not waste, use them for scrappy quilts, I've made several Mile a Minute quilts with the long strips of scraps, that I have either given to family members or charities. They come out great. If you google Mile A Minute quilts you'll find some pictures, there are endless ways to use the blocks. My favorite is to alternate a white on white fabric block with the scrappoy block.
Also I save all the batting scraps & fabric scraps that just can't be used in quilts & stuff them into a simple denim or heavier type fabric pillow cover, sew the opening closed & donate them to the animal shelter for pet beds, the shelter loves them.
