I cut scraps into 6.5" squares, 2.5"x5.5" strips, and 2.5" squares. What I have left that is too small to fit into those categories I keep if the pieces are at least 1" wide. That gives me a variety of sizes for scrap projects. This way I can cut the 6.5" squares into smaller pieces if needed, and I can cut the rectangle into 2 2.5"squares if needed. But scrap management takes time!!
