I'm willing to join. I have so large a stash that even with it organized by color, I frequently forget that I have different fabrics. End result --- I sometimes end up rebuying what I already have stashed when I don't need the fabric.
I also have a huge file of UFOs packaged with their fabrics -- that doesn't include the quilt kits I've purchase over the past few years.
A 12-month moratorium of buying more except for bindings or backings will be great. So count me in.
