My stash has grown but then I started quilting about 5 years. My stash is still small (might fit in 2 containers) but my UFO pile is the problem. I have promised myself to fix the UFO pile before starting more projects. But I keep adding to the stash for my future UFOs so it continues to grow.
New plan is to start a new project and finish two UFOs before starting another new project (or buying more fabric) ... will have to see if this plan works for me.
