I am one of those, likke many here, who needs a clean area in which to work. I can't start a project unless everything is put away and the room is clean, at least for the most part. I don't mean white-glove clean, though:D
When I'm working on a project, I usually just straighten everything up - stack rulers, put cutters and scissors away, tidy up fabric, etc. I usually work on only one project at a time, too. That makes it easier to keep track of it all.
