I think this all the time, then it's time to start my next project and I just have to have a specific color or print so I go buy more. I keep telling myself to stop buying more and more, but I know I won't listen. For example, I'm heading to Lancaster this week. I know I won't come home without more fabric.
I make a lot of controlled scrappy quilts with left overs from other projects and yet my stash grows and grows.
