I'm doing sketches for a book that will have lots of illustrations of things that happen in this particular classroom. Some action will take place in the front of the room, some in the back, and some in various corners. It finally occurred to me that I needed to do a floor plan of the room in order for the illustrations to make sense and work together. I cannot begin to tell you what a bad sense of direction I have – and how many times I had to turn the plan upside down and sideways, and start over. I'm glad I'm not an architect.
