I love to draw and have done so most of my life and yet have known so many who say "I can't even draw a straight line". I have found this book to be a great and simple manual to teach out of. I have personally known both adults and children who found the artist within from using the Drawing Textbook. This book gave me a way to explain some concepts simply that I didn't have the words for. To be able to do, but not be able to understand HOW has been the chasm around drawing101. This book is your bridge over that chasm. It is great to teach out of, but I doubt a child would want to pick up this book on his or her own, to learn out of that isn't talented to begin with. The feel of it seems more mature than that.
For those who can draw well, this book was not made for you. It was made for beginners and those who look at drawing as something "talented" people do. It is made for teachers like me who need words to describe things they know how to do. If you fall into one of those categories, I really do not think you'll be disappointed.
