crumplemeone now crumpling up wax paper or splitting a seam on his pants?
You'll probably want to do this on wax paper for easy clean-up.
Draw a design onto a piece of wax paper using a grease pencil.
Paint each section of the wax paper with the relevant color using a small paintbrush and careful strokes.
Allow the paint and glue to dry undisturbed on the wax paper overnight.
