My sewing room is three fourths of my basement, so it is a very large area. I try to keep it relatively organized all of the time. But I have the bad habit of pulling fabric out of the closet and stacking it on the cutting table for auditioning, and then not putting it away. So when the stack threatens to spill onto the floor, it gets cleaned up. But my usual plan is to clean and organize after each project is completed and before the next one is started. I find that I don't get anything accomplished if the room is in shambles, so I try to keep it clean.
