I truly only save my batiks and then I cut them at 2 1/2, 2, and 1 1/2 squares for scrappy projects. Weird triangles I toss. I don't keep leftover batting smaller than about 7 1/2 inches. The batting, I use in quilt as you go, Fun & Done patterns. One of the greatest gifts I gave myself over the years is if I purchase a kit or collection and make what I want to make, I put the rest on the free table at Guild. Someone almost always takes it and makes baby blankets, placemats or whatnots.
