Oil. For a Christmas gift I was asked if I could paint on a plate. Well, not knowing if I could or not I told my client I would give it a try. Never had the experience of painting on a surface such as a plate. It was a little different than a saw. I did have to prep the plate and did experiment to get the feel of the surface. The clients mother owned many dogs in the past and every one of them she commissioned someone at the time to paint each on a plate. Little Marley was a Bichon Frise and loved her bed with all her toys around her. It was a commission that gave me a challenge but an enjoyable one.
