What to Draw and How to Draw It by E. G. Lutz is a great drawing resource written especially for children.
This is really a remarkable book in which line is made a good reason for form. The youngest child may grasp the magic progress of this way of working and he will draw the picture naturally and well.
There are very few instructions, the focus being on the object and the step-by-step addition of lines. This procedure, the book claims, allows the physical skill of drawing and the knowledge of proportion and form to develop naturally.
The drawings include cats, fish, frogs, cows, dogs, horses, raccoons, squirrels, beautiful cattails, and many, many different types of birds, making this resource a great addition to nature studies!
