Using different mediums and surfaces is pretty interesting. The linin canvases I've been trying out seem to have a different feel while painting from the canvas boards. The paint seems to sit nicer and smooth out nicely. Considering the paint is just sitting on lots of gesso, the material under it shouldn't matter all that much. The linen isn't as tight as the board though, so maybe that has something to do with it.
