This art on cardboard has everything on it--oilstick, ink, acrylic, watercolor, crayon, enamel, glitter. What can I say...it went through many transformations. I had the painted cardboard sitting around for about a year. I used it as a paint palette for another piece of artwork I had been working on. As I was cleaning up from my other project, I looked at this piece and liked the splotch of black ink on it. I had an idea and just kept working it until I got to this finished piece. Actually, this angle doesn't show it well, by the two faces work separately as well as together.
