I remember a studio art class I took and the teacher had us doing just about everything using Sharpie on sketch paper. I guess he wanted us to get used to putting in what's visible and not trying to play with layers, shading, erasing, etc. To train the visual system first, and worry about the fancier stuff later. It made a lot of sense and it's sort of like sending new cinematographers off with a silent super-8 camera and telling them to work on story, lighting, and framing rather than worry about color, sound, dialog, etc.
