Glad to see this topic. In Hobby Lobby the other day in the remnant bin I saw a piece of fabric I liked - 54" wide, one yard piece - looked like cotton - I found the bolt of it in the decorator section and it is 100% cotton, but it is treated to help reduce staining. I thought I would use it as purse lining - or wonder if whatever they put on it would wash out. It feels just like regular cotton.
