Intaglio
A printing technique I learned in college. You take black scratch paper, a drawing, and a wooden stylus with a sharp tip. Then put the drawing on top of the scratch paper, use the stylus to draw out whatever you like. Remove the drawing, and you can go over any lines that were not completely removed. You must be careful with the scratch paper as it is easily scratched. Even so, you can adjust the composition.
