Ah Dawn the old this is therapy vs you need therapy dilemma. For me it depends on how recently I have blown money on fabric I don't need.
Par for the Day: I am with you, I don't buy fabric unless it is on sale, but with the internet you can almost always find something on sale. Right now I am holding the line at $5 a yard, so that limits me a little. It is still amazing how much fabric you can find for under that price.
