So there are rules....These are the ones for this rusty paper. The images emerge from the rust itself. I don't pre-plan them, but look at the paper, and see what kinds of folks are there. Sometimes I lightly sketch one out with pencil, but then when I come back to it later (a different day, even), it's someone else there, and I go with that. And then I use a dip pen, with the same nib, and black India ink. I so want to use some kind of black wash, but that's not in the boundaries.
So if these people look a bit skewed, know that that's the way they came out of the rust. All of them are "doodles", in that I just played around with the forms. No models here.
