I did this on Judson's Guerilla Carton Board. Carton needs an accent mark, but I will have to wait till later - it's late and I'm sleepy and don't remember how to do it on my laptop. This surface is wonderful for oil pastel - it's really a love affair between the two. If you use oil paint, it's good to apply Gamblin GAC before painting on it. I usually bond the carton to painting panel or mat board. I don't know if artists appreciate this lightweight board/paper, but it's wonderful! It's archival and so lightweight - plus I just swoon over how wonderfully it works with oil pastel! This drawing is on 10 x 8" carton. Try this surface - it's really great! Thanks so much for stopping by!
