I'm making a puff quilt using left over fabrics, and bits of left over batting. I cut flannel or muslin 4 1/2 inches square. Then I cut fabrics 5 1/2 inches square. Pin the corners together. Pin the sides, making a tuck to make it fit. Machine sew on three sides. Stuff with some batting, and sew the last side together. These puffs can be joined into any size. Colors can be matched, if you want. I line the whole thing and tie in the centers of the squares, to finish.
