Found this neat board when I was in Chicago a few weeks ago. It was a canvas board with a cradle (?) Thought I would give it a try. It was different. I almost pulled out my acrylics. It didn't respond to transparent wc like paper does. It would even lift off. That would be great if you made a mistake. I just wanted to paint thick on it. I am going to do this composition again but on paper...watch for it.
