I'm getting all kinds of lovely pictures in my head of the spectacular quilted wallhangings that could be made with these!

Have you determined what the fabric is made of? Type "burn test" into the search at the top of the page, and there will be lots of threads on how to figure it out.

Before making any decisions, I'd find out what I had, and whether it was colorfast.

Oh, it would be a gorgeous quilt or summer bed coverlet!
