When I took up quilting about 4 years ago, I lived in a house that did not have much room for sewing ( a small nook in my kitchen). My stash all had to fit in a wicker basket/coffee table. I didn't have room for things to accumulate, so I just made a commitment that I wouldn't start anything new until I'd finished what I was working on. Even though we've retired and moved into a bigger house, I'm trying to stick to that. I took one of the bedrooms and converted it to a sewing room. I am beginning to accumulate extra blocks and squares (I sometimes change my mind mid project), but so far no UFO's. I will say my stash has exploded, however. No longer fits in my basket alone.
