I have been tying flies for about 12 years and will always tie flies. I tie for my fishing and I tie because I love to tie flies and it is relaxing for me. I enjoy the creation part of tying. If I see a fly in a book that I think would work for my style of fishing, I can sit down and tie it. That gives me great satisfaction. I do not care which way, tying or buying, is cheaper. My personal opinion is that to purchase my flies I would need to have the cash in my pocket at the time I needed them and that is not always possible. The set-up cost for tying your own flies is all up front and from there on it is will not cost you anything for a particular fly except your time. Tying material goes a long way and will tie 100's of flies before need requires another purchase of the material. If you only tie for your own needs and for your local waters you will not need a huge selection of tying material. If you tie commercially then you will need tons of material and that is a whole another story! I still have more tying material than I will ever need, but, this is my hobby and it can never be taken away from me except by the Almightly. I love it so much that I have been teaching beginning fly tying twice a year at the local college for the past 8 years and love and look forward to each class.

Fly fishing and fly tying are two things that I do, and when I am doing them, they are the only 2 things I think about. They clear my mind.
