I'm one of the few who does not have a 'stash' per se. I typically buy for projects but I usually over buy a bit - if I need 1 yd I'll usually get 1.5 yds so that I have room for boo boos. As such I have bits left over that are a stash of sorts. Enough if I need to make up a block for some reason or if I want to try new techniques or patterns. It works for me. I don't have room for a stash and I'm not a scrappy quilter so it seems to work. I enjoy the process of selecting fabrics for a given project. If I had a stash of smaller pieces I'm afraid I'd never have enough of the given fabric that I wanted. I'd go for it.
