David, if you are going to be serious about tying, you should purchase
Ted Leeson's and Jim Schollmeyer's book "The Fly Tier's Benchside
Reference". Anything you ever wanted to know about fly tying is in
this book. It's a wonderful reference manual with step by step
illustrations on hundreds of techniques and dressing styles.

When it first came out in 1998, many of us rushed to the book store to
buy it for $100. Today you can buy it on Amazon.com for $63. I saw
it in a fly shop recently for $60. Great buy.
