Bob, you don’t need a steady hand to draw a Photoshop “path” around an object. You place points one at a time around the object you want to cut away from the background. The lines can be straight or a Bézier curve. And once you’re done, you can go back and tweak the path by moving any single point slightly. No steady hand required.
In the F3 photo above, I had to draw a path around the locomotives, and that included the horns and the tiny American flags on the top!
