Sources for Forms
Remarkably, most parents feel there is a "specific guide" to teach the "mysteries" of form drawing. Initially, it was translated as Form Designing; the simplicity of the name of this way of drawing is the answer to the mystery. You are simply designing and then drawing forms!
Once that realization is established, it's easy to locate sources.
