This is what I do, and I do save the batting scraps! The smaller ones I use or donate for pot holders, hot cup wraps, and such.
A friend of mine gets batting scraps from others, then cuts them into squares; she'll pair two half-square-triangles (right sides together with the batting square on the wrong side of one of the blocks), stitch them together (with an opening), turn them inside out and fuse the opening shut. She has a never-ending supply of these stuffed blocks, which she sews together to make perfectly reversible quilts of varying sizes. She finishes the quilt with a simple stitching along the diagonals of the blocks.
