I took a bunch of the leftovers from my bedspread and sewed the together until they were 20x36 rectangles. I sandwiched them and went to town quilting them. I tried to use a different pattern on each fabric. It was a nice manageable size and the constraints of the piecing made a good design challenge. When I finished quilting them I trimmed to size and put a simple envelope closure on the back. A quick machine binding and I was done.
