I don’t buy fabric to stash but I do buy a little extra 1/3-1/2 yard when I buy for projects. I didn’t realize until recently how much of a stash I’ve built up. I’m using that along with all sorts of other fabric given to me by a close friend to make the books for a bookshelf quilt. Some of it I would not use itself or create a quilt for those fabrics but as “books”, they work perfectly.
