I've also been trying to not buy fabric on impulse just because I like it. I don't have a stash anywhere NEAR what a lot of people seem to have but it's bothering me. I need to plan some quilts for what I have and get it cleared out.
I've only bought fabric for two quilts in the last few months and the one I am working on now is from what I already had.
Good for you and hope that you make some great quilts to share from your stash.
