This is about a 4ft circle, maybe a little larger. I made the canvas by attaching wood to a circular metal joint. My dad is a welder and he had some. It's like angle iron except in a circle. Then I stretched the canvas and so forth. I think they sell pre-stretched canvas like this now, and maybe they did then too, I don't know. Anyways, I painted this thinking I would never sell it and it was gone in days.
