Our Project Linus chapter got a recent donation with lots of these beautifully embroidered squares. There is plastic on the back -- some sort of stabilizer? -- that makes the blocks crinkly when you bend them.
What could/would someone use these for? I thought coasters, but the edges aren't perfectly finished, although they are almost completely satin stitched. Some white interfacing shows through.
It looks like someone put a lot of work into these (there are a lot of them) but I don't know how to put them to use. Any advice is appreciated!
