First, the best place to look for information is from fellow anglers. Check with local fly shops, Trout Unlimited chapters, & sportsmen's clubs to see what's going on in your area. Many groups & shops offer fly tying lessons for beginners - usually for a small fee to cover the cost of materials used, etc. This is a great place to start because nothing is better than having someone who knows what they're doing showing you the ropes. You'll meet new people & get to see flies being tied.
The next aid for you would be a good book or two. You'll want some books on your shelf as you tie for references to check back with as you progress. There are tons of books about fly tying out there & many of them are good. So, I'll just suggest a few to get you started.
1.) "The Complete Book of Fly Tying" by Eric Leiser. This is one of the best books for beginners & intermediate tiers. It has everything you need to know & is a book every fly tier should have.
Fly tying is a nice activity that will enhance your enjoyment of the sport. You'll learn a lot about fishing by doing it &, I'm betting, become a better angler because of it.
