doubtfulguest, have you seen the book "Drawing on the Right Side of the Brain"? Your DD is already so awesome at her art, I'll bet she'd get right into that method! It's about (at least at the start, I've never been through it to the finish) drawing the negative space -- like the shape of the air in between the slats of the chair, for instance, which of course yields a picture of the chair in the positive space. I am abysmal at art, and I've always enjoyed trying things the way it shows in that book.
