This is such interesting info for me reading the replies. My stash is still pretty small. Anything FQ or larger, I've folded and have in one bin. All of the smaller pieces in are in my scrap box. Not sure if I'll ever do a scrappy quilt, but should I decide on one, I'll be ready.
Plus other fabrics that I've bought for specific projects are grouped together in their own project box and marked as such.
