Trudy nicholson is a very seasoned and amazing scratchboard artist. I watched her work once, she makes very established sketches before starting on scratchboard. She also had some transparent films that you sometimes see in a pasta box, and put ink hatch lines on several sheets of them. Then, she will "Preview her cross hatch on a scratchboard by placing those transparent films with ink lines on top of the scratchboard, testing out different combination of angles and thickness of hatch lines before actually touching the scratchboard.
