I used the bulk of my batting scraps to make baby quilts using quilt-as-you-go methods with a small block size. I think the last one I made had a four inch block. I will also use them with fabric from sale fat quarters to practice my FMQ on. I use 100% cotton batting, so anything smaller than that goes in my compost heap. I will stuff them into a lingerie bag and wash them first, but at least I'm not throwing it away.
