Gotta agree with Lotech.
I didnt necessarily follow Al’s tutorials word-for-word, but they WERE one of the biggest things that changed my attitude on tying flies from, “That might be for some guys, but not me.” to “Hey, I think I might actually be able to do this!”
Once I decided I wanted to tie, like most of my endeavors, I read. Alot. I read anything about fly tying that I could find, and remembering Al’s tutorial, I read it ALOT. Read it and re-read it to the point that I knew how to tie most of the first half of the beginners series before I ever picked up a bobbin, even if I didnt actually know if I could.
Like others have said, start simple. I wouldnt even worry about dries for a while. When you do, I’d suggest getting a good quality grizzly saddle to start off with (even a 1/2 or 1/4 saddle if you want to same $$ in the short term). I started by tying a beginners’ adams: moose mane tail, gray body, and grizzly hackle, no brown. The saddle hackles, for me, were much easier to work with, and the longer feather allowed be to dress flies with heavier hackle if I chose to.
Dont worry too much, you’ll learn at your own pace. There’s patterns that stumped me as a beginner that, when I revisited them months down the road, I magically would be able to tie them. Basically, my abilities had improved in the mean time.
Also, the bit about the mentor is invaluable. There’s a HUGE time difference between turning and asking “How to you do hackle nymph legs?” and tying a few dozen shoddy looking nymphs before you finally get it…sort of…
I tied for a while with a very accomplished tyer, and the experience was great. Not just for the tying instruction, but the conversation at the vise and the amount of fishing knowledge gained. One of the most overlooked aspects of fly fishing/tying, IMHO, is, “Okay, you’ve got these nice-looking flies you tied up…how should you fish em?”
A mentor helps with that considerably.
