Those rules sound great. I have to say that my problem is I buy fabric with a project in mind, then a few months (or years later) I cannot remember what I bought to go with what. I then am afraid to use the fabric because I KNOW I intended it for some project and if I use it, I might regret it later when I remember why I bought it in the first place. I am getting to where I write down what I want to do with the fabric and tacking it to it so that I can remember what my thinking behind each piece I purchase was.
