Absolutely, but that requires advanced fine motor control, understanding of how the instrument lays down color and what multiple layers of color look when on top of each other, and so on.

The naive way to use the instrument, is to run the instrument over the area one or a few times. The simplest way to do that in terms of motor control (e.g. fewest turns) is to run it up and down the longest axis one or more times. That's exactly what a child does.
