Not an exhaustive, or even organized, discussion of Fly Tying.
But a few things I wanted to comment on, in no particular order.
It's all been written down! There's nothing new in fly tying, you just need to find the right Books! Check out my Fly Tying Book Recommendations!
OK, if I had to give just one instruction to newcomers, it's this. Never tie just one fly...
Minimalist Fly Tying Kit
What if you didn't want to tie a whole bunch of different flies, you just wanted to tie one or two patterns? What would be the minimum kit necessary to accomplish that? For instance, if you wanted to tie flies on an airplane? Check out my discussion here.
Here's how to use my Gap-A-Matic 3000, the amazing salmon fly proportioning device. OK, "device" is maybe too strong a word... And maybe "amazing" is a bit on the excessive side, too...
I think you all know my opinion on whip finishing. Just do it. Stop whining about half-hitches being just as good, etc., etc. Just do it. We've taught young boys and girls to do this in minutes.
Buying a whip finisher. Just buy the Matarelli.
Note that I didn't say Matarelli-style. Get the real thing. There's a difference, really. Save your time and money and don't mess with anything else. (I am seldom adamant about tools, books, etc., but this is just a weird thing. You can buy a half-priced knock-off, and while it works, it's just not as smooth - the slightest bit clunky. Multiply the 0.375 seconds you waste, times the 50,000 flies in a life time, and buying that expensive Matarelli is a great investment!)
As an aside to the above paragraph, I still don't think that a tool that simple could show that much difference between the knock-off and the real thing, but it's true. Take a look at this photo of the knock off on the left, and the real thing on the right. It has everything to do with the weight and finishing of the hook end, as well as the dimple in the folded bar. In addition, the "bearings" in a Matarelli (or the hole in the handle) fit the shaft better. The Matarelli will spin for several seconds if you spin it, while the knock off will wobble just for a second. This translates into a smoother wrap. I'm not making this up.
I find that the easiest way to use the Matarelli is just how the inventor intended you to. Here is a link to the original instructions:
And just to be fair:
Personally, I go back and forth on magazines. Every time the renewal card comes in, I ask myself, "Did I get $19.95 of value from this over the last year?" It shouldn't be a hard question, but sometimes I can't answer in the affirmative! Right now I just subscribe to two magazines:
Fly Tyer Magazine. A US based quarterly.
Fly Dresser. The Journal of the UK Fly Dresser's Guild
Both of these are nothing but fly tying. I can recommend them both.
OK, Materials. Where do I get stuff? My first advice is always, "Right down the street." Support your local fly shop. For those of us in south-western NH, that means Sam's Sporting Goods in Keene or Brattleboro, Pelletier's in Jaffrey, and Frenchy's Fly Shop in Keene. None of these guys have really exhaustive supplies of anything, but they may get you by in a pinch.
In terms of mail order, I don't really have much expertise there. Since I have a few wholesale vendors, they get most of my business. Because I tie mainly classic flies, I can recommend Castle Arms in Springfield, MA, as well as John McLain at FeathersMc. Both of these gentlemen are a pleasure to work with, but cater mainly to the salmon fly tyer.
(Note that neither of the above links point to very vital web sites - I should talk - but my understanding as of early 2017 is that both are still viable options. Give them a call if you have problems.)
