This is where the magic happens :->. Notice the thin boards surrounding the easel and the current work. I use those instead of a mahl stick to keep my hand steady. They work well because I never have to worry about where to place an end on a dry spot. The computer shows me various views of the work in progress, and with Gimp, I can get measurements for placement of things on the canvas. I usually have one full view, one view zoomed into the area I'm working, and one view in Gimp. I use Linux, so having all those views available is easy - each one is in a separate workspace which can be displayed with one mouse click.
