Cross Contour Drawing - What is Cross Contour Drawing?

Cross contour lines are drawn lines which travel, as the name suggests, across the form. Cross contours may be horizontal or vertical, as on the right side of the example, or both. Often, in more complex forms, cross-contours will be drawn at varying angles. In this rather lumpy example, the grid of cross-contours looks a bit like the gridlines on a globe or a diagram of a Black Hole in space.
