Here is the painted clayboard version of my drawing "Cacao." (Sketch shown earlier.) I used a combination of media to paint. I started with watered-down acrylic paint but found it too thick and opaque like gouache. I finished it with something that seems to be working well: Ink with a wee bit of acrylic to stabilize it so it doesn't drip too much but not enough to take away the luminosity of the transparent ink. This was a two movie painting process. "Nine" and "The Secret" which, strangely, seemed to have similar ideas behind them.
As you see, I don't paint a scratchboard engraving the same way I would if I were intending this to be a painting on its own. Everything must be darker and more full-bodied because when I begin engraving it the white clayboard that is revealed will lighten everything.
We shall soon see how this one comes out. There is a bit of a surprise element in this work, just like with my kirigami papercutting. I never know what it will really look like until I'm finished.
