Spread out, make some room. Get out everything you think you’ll need. You are in your space, so make yourself comfortable. Have plenty of rags handy. It’s OK to have crap all over the place when you’re working. When you’re in the middle of a task, you grab things, put things down, and your focus tends to me more on the problem than the organization of the space around you. As you develop a style and pace of movement, you’ll find your natural level of mess while working. Some people are more comfortable in the immediacy of clutter, with everything close to hand. If that’s you, let it work for you. Don’t assume a messy workspace equates to careless craftsmanship.
