Since none of them matched each other, I couldn't use them for bags. But I did think they would work well as pillows, or maybe as a large floor-sitter. I sewed eight of them together, four for each side, and Mr. Fixit bought a 30-inch piece of 3-inch thick foam for stuffing. We had to trim it a bit, but the two of us managed to get the foam into the pillow sleeve. I sewed up the last end by hand, after vacuuming the bits of foam off Mr. Fixit. (They like to cling.)
Here is Dewey trying it out.
