It was originally designed based on our very popular drawing workshops that we do across the country. It is a book teaching technical drawing skills to use with your student when they want to know how to make something look real. It is progressive so it starts at the beginning of shading and shadowing techniques and goes into intricate drawings of animals and people. Drawing people, drawing technical perspective and landscapes, shading, atmospheric perspective, using a grid and window to draw and more are covered. Don't miss this book. If you don't feel adequate to teach drawing for only $20.00 more you can purchase a video by Sharon Jeffus that will walk you through the book.
