I'm wondering if anyone has tried using a version of the clear viewfinder
that Betty Edwards speaks about in Drawing on the Right Side of the Brain.
This is the viewfinder that she uses to do a contour drawing of your hand by
placing it under the clear material. It supposed to make the 3-d to 2d shift
easier to understand.
I"m thinking of making a classroom set using matte board and some acetate.
Does it help the students?
