My 2 cents... I got into tying because flyfishing was more than a new way to catch fish. It is not cheaper than buying your own flies. It is a way to connect even more to the sport your love. It got me interested in entomology and the overall environment fish live in. If the first fish you caught on a flyrod made you feel like this first time you caught a fish... flytying is for you. If not no worries. Many places sell flies for as little as 49 cents. That is dirt cheap. However, you cannot put a price on the feeling of being streamside when the fish are eating # 18 tricos and you have nothing close and tying a half dozen on the tailgate of your truck and slaying the next day. Truthfully, tying flies has opened my eyes to patterns not commercialy available that are key to success in certain waters. It is in my opinion a dimension of the sport at least 50% as satisfying as the act itself. You are thinking about the pattern and how you will fish it even before it hits a flybox. It supports small local shops and keeps you involved. It's a lot like pizza.. even when its bad it's still pretty good. You will see and meet tyers who are gifted beyond belief. You will come up with a pattern you will fish with a confidence you never had. Try it out.. it's a beautiful disease!
