Now that I like all the elements of the draw and their placement I can rub charcoal on the back of the paper and transfer it to a board for painting on. This board was fairly smooth and had a couple coats of Kilz primer on it which is as flat a finish as paper. As always the board is recycled wood. If you are careful you can do a very nice charcoal drawing on a board prepared this way, but you can't do any erasing. However mistakes can be painted out with more primer if need be. Then I spray the board with workable fixative and she's ready to paint.
