More fun with china marker resist... I like the freedom of not knowing how the lines will look until the moment when I wash over them with color, and at that point it is too late to change them. The white waxy marks are nearly invisible on the white paper, so all I have to go on is a memory of where my hand has been.
With other kinds of drawing or painting I have more sense of how the piece is evolving while I work on it, and I can make changes and corrections as I go along. In contrast, this process is mysterious and awkward and sudden.
