I agree, buy what you need for a project instead of building up a big stash. I have a stash and find I always need to go out to buy more because either the piece I need isn't big enough, or don't have enough coordinating fabrics to go with the one I chose for my focus.
Also, try to machine quilt on your home machine. It isn't as fancy; but I personally like the looks of it.
Some gals on here are selling stuff from their stash that they don't want to use, that is the downfall of having too much. I probably won't use all mine either...we just fall into a habit of gotta buy it lol.
