If it isn't affecting your work now, I wouldn't worry about it. People just have different habits when they work. I have a dear friend whose sewing room is chaotic, with bits and pieces of her current "idea in process" scattered everywhere. There is something about it that appeals to me but I tend to put things up when I'm done with them, keep the surfaces clear. Like you, these are habits I learned in childhood. But they are just processing habits. None of this prevents you from making beautiful quilts. It's all in what's comfortable for you.
