The idea of a scrappy doll quilt is a good idea, especially when you get to experiment with a new technique such as free motion quilting ... enough to get a feel for it, but not so large that you can't made swift improvement or become discouraged ... good plan!
May in Jersey, you are a good encourager <g> Just send those little ones on to a thrift store, or check with your local quilt store. Our local quilt store has bins for two or three groups of quilters who need donations - - Project Linus, the high school home ec class, the American Legion Auxiliary, and a couple of others ... people can put their scraps or anything they know someone who does charity sewing and creating, and share ... maybe they will help you get your unused scraps to a quilting group that will turn them into something else.
