The right kind of paper is the paper that is right for your needs. A paper that behaves just the way you like it to act, this is very important to your direct action at a given moment. One cannot stress this point too lightly, often the difference between a successful attack, or a rout. Remember the brush need not rub the paper at all, so to say. You mix the wash that you think will match the tones in the object, or objects you are looking at (notes, April 6, 1977).
