Not enough hours left in this lifetime to do all that - I keep my stash "meaningful", group them into projects (changes are made when I get new fabric), or store them in themes (children, blenders, batiks, etc). I photocopy fabrics and cut them into mock-blocks to put on a design wall and see if I like what I'm attempting before I start cutting, and I'll take some of those paper pieces with me to buy backing and binding fabric. My goal is to never have so much stash that I don't know what I have, and I promise never to make the same thing twice unless I am prepared to do them both at the same time. Should that ever change, I'll go digital.
