Since my 'sewing room' is in the Great room or family room, I have to clean up every time. Even if I had my own room, I think I would because my mind and body operate better when I am organized and tidy. I don't spend time I don't have looking for things if I put them away where they belong to begin with, I don't step on pins or scissors, my fabric is color coded in bins and I can pull out the drawer I need, and I don't have to hunt around for my tools as they all have a place and are in it.
