Be sure to check out the new book from Tim Cammisa if you haven’t already. This is a nice, well written book that helps you improve your fly tying and includes step-by-step instructions on how to tie popular patterns in various categories including dry flies, nymphs, emergers, and streamers. I would highly recommend this book for beginners. Here is a snippet from the introduction.
“Learn a broad range of techniques for dry flies, streamers, and wet flies by tying the modern flies that everyone is talking about. Author Tim Cammisa teaches you how to tie these simple but effective patterns and then how to take the techniques you’ve learned and use them for most of the other core patterns—old and new—that should be in your box. Includes information on the latest materials, tying tips from other tiers, and 16 patterns with recipes and complete step-by-step instructions.”
