Gary Greene explains so well how to use water soluble colored pencils. I was hesitating to use mine, thinking that learning to use them would be too complicated. Oh, No No. Think again. They're just fine. I'm glad this book has so many examples. It's all right that some subjects are used several times (such as the cherries), because each time there is something new to learn about the application of the pencils. So, each example is making a certain point and each serves a purpose. I like this uncomplicated book!
