lines, dots, and cross hatching.
This design was created by drawing in clear glaze pen on white paper, letting that dry, and then coloring over it in water soluble marker pen. The water pens can not penetrate the dried glaze, so you get a pattern of color with white (or at least lighter) stripes within it. Finally the black outlines are drawn on top of the completed art (because it is easier to get them right after the colors are in place). (file L67k2)
