I would much prefer to have no stash and to buy what I need for each project. A stash presents a storage problem for me. My experience is that what I have is either not quite enough, wrong shade, or sometimes too big a piece that I hesitate to cut into it. Also, my taste changes and what I thought was gorgeous today, I may wonder "What was I thinking" next year. There is no way not to have a stash because we always buy too much when starting a project for fear of running short.
