Query: Great starter book. Step by Step

Yarnell makes it easy. He covers everything including materials and terminology. The step by step leasons are easy to follow and provide a wealth of information from which you can build your own skills and learn the basics to experiment on your own. I would also suggest Yarnell's videos, one in particular covering techniques so that you can actually see what is going on.
