When using marker in class, I like to encourage students to try applying additional layers. It tends to deepen the color and lessens some of the characteristic streaky texture that marker is notorious for. Some colors and brands benefit more than others. Black, for example always seems to look richer and less…marker-ish. I give a quick lesson early on and emphasize that one should allow the marker layer to dry thoroughly before attempting a 2nd coat. Waiting until the following day is best. It becomes a handy technique particularly for students who finish a bit early and need an additional activity. In the picture, the upper right corner has a single layer of marker coloring while the rest of the drawing has a second coat. The markers used were Crayola cone-tip watercolor markers in the non-washable variety.
