Shane,
It’s way cheaper to buy your flies.
It has always been cheaper to buy flies.
Yes, you can tie flies for less than they ‘cost’, but you have to spend a lot of money and tie a lot of flies (many thousands) BEFORE you will realize any return, and this does NOT include anything for your time. If you figure ANYTHING reasonable for your time you are FAR better off, financially speaking, buying flies (given that you CAN actually buy them).
Most of us tie flies because we like to do it. It can be fun. It’s certainly relaxing. It can be a way to be creative without dealing with harsh critics (fish are pretty forgiving, and on a fly you and the FISH have the only opinions that really matter).
If you tie your own, you can get the flies you actually want, made specifically for a given situation, with all the attributes that YOU want in them. I seldom fish with a fly that you could buy in a fly shop, or that anyone in a fly shop would recognize.
The bottom line is that you need to decide if this is about the money or about the fun/creativity/challenge/satisfaction.
If it’s about the money, spend the time you’d spend tying flies working and earning money and buy your flies. You’ll not only be ahead, you’ll be far enough ahead to book a couple of guided trips a season, or a ‘destination’ trip every other year (you know, tarpon in the Bahamas or Peacock Bass in the Amazon, things like that).
If it’s about the rest of it, then slow down a bit. Pick one fly, your ‘favorite’, and get the stuff to tie it. Tie five or six dozen of them, or until you can tie a dozen of them and can’t tell them apart, whichever comes first (on all the ones that you CAN tell apart, cut the stuff off the hook and reuse the hook…you want to fish with only your ‘best’, both you and fish deserve no less). Then pick another pattern, buy the stuff to tie that one, and do the same…
After you’ve acquired several flies that you are comfortable with, catch fish with, and feel you can tie correctly enough to suit YOUR expectations (you and fish are the only ones who matter here), then you’ll know if this hobby/passion/addiction is for you or not.
If it’s not, it won’t matter, you’ll give it up and save time and money.
If it is, you’ll not care.
