I have my grandfather's WWI wool army blanket; mended, darned, patched relic that it is. I suppose it could be used as quilt batting, but it means too much to me just as it is that I will never hide it away inside a quilt. It proudly lives in my truck "in case of emergency".
I got a good giggle when you said you could get a deal on "new vintage" wool Army blankets. Bit of an oxymoron don't you think?
