I will admit that I am a slob....I usually have material tossed on my dining room table...the only time I really clean it up is when the following happens
1. I know I am getting company and we need the room for eating.
2. It is really bad and hubby bribes me by saying you can go to JoAnn's and get more fabric if you clean this up.
3. I slip on a piece of fabric that is on the floor from doing paper pieceing (I have hardwood floors)
Other wise I leave it. There are times I will clean up in the middle of a project if I cannot find something
