It depends on how messy the space is. LOL I am a bit OCD so want to be able to find things easily. I try to clean up after every sewing day, but sometimes it is the scraps that get away from me. When the box gets full, I try to spend a day cutting or organizing by color, or I will never use them. My DH just put in a new floor so everything was removed and put back in the course of a week or two, so I re-organized then.
