Doodle some scribbly elephants in your sketchbook. Pick the one you like best, and scan into the computer. Enlarge to fit nicely on an 8″x10″ paper; print (I printed on 140# Fabriano hot press watrcolor paper, but any paper will work).
With a black permanent marker, draw in curvy lines around the existing lines. Think "thick & thin." Fill in the thicker areas.
Paint a light layer of watercolor, using several colors.
Using markers and colored pencils, color in your elephant with lines, dots and patterns until you are pleased.
Here is a detail.
Finish with a white paint pen. Add dots along the black lines, and any other place you feel needs a little white. (Note: This project first appeared in my book "Drawing & Painting Imaginary Animals."
