I started with purchasing for specific projects, then noticed the "sale" bins and started adding markdown stuff "just becuase", then it was onto Ebay- again, specific needs first but then when I joined here and saw what a stash really meant. I knew I need to get serious and get some real stash. So I bought "fabric bundles" and "fat quarter bundles" on Ebay and going to the thrift store (I've found some fabric there) and yard sales. I think I'm finally comfortable with the amount of stash and now I'm working to reduce it.
I, too, am a fabriholic, it is terminal, there is no known cure but not life threatening. There are those of us who are still in denial, but when you come out of the closet, it feels so much better.
