I use scraps for paper piecing projects. Most of the spaces to be covered are small and then I seldom need to cut into large pieces of fabric for one of my little paper piecing projects. I always have a paper piece project on the go and try to use a lot of my scraps as I accumulate them.
Paper piece projects can be made into lots of things, other than quilts. I've appliqued them to blouses and jackets and made mug rugs and candle mats using them as the center focal point.
