Biggest part of my money goes for hooks and beads around 150.00 a year.I tie size 22 to 14.I spend about 50.00 buying foam hoppers and streamers......aurelio

I don't really think about how much I spend on tying materials, I just like fishing with flies I've tied myself.

When I drop into any of the local fly shops, I'll drop a little bit of coin on certain dry flies, but that's about it.

I tie for my old man and myself. I'm hoarding a small stash I inherited from a local who passed his widow let me buy it all for 20$ but I had to remove it right than. I took his whole tying room anf stuffed it into my 68vw bus. And it really helped me improve my tying skills having someone who tied before me who had organised and amassed gobs of great materials. I only buy hooks and synthetics cuz this unknown man hooked me up in his death more than any blessing I could have asked for. I guess what I am saying is amass a collection so this thing called fly tying can propriat in the generations to come.

Two approaches to fly tying - necessity and relaxation. I'm a hand-to-mouth fly tier and motivated by the former. My buddy Mick is the latter - he ties flies for fun and will never utilize the stacks of filled fly boxes. He has probably devised a way to keep them out of his wife's sight, as he did with rod tube racks.
He jokes (partly) that when he took up fly tying and inventoried his first full fly box, it only cost him $115/fly. He never did that math again.

It's probably more like manufacturing integrated circuits, though, The first one costs millions, after that each costs about a nickel.

It was probably more like $115 per fly for the first one of each pattern; after that each was almost free, except for labor.

this, mostly. Pretty much the only new materials I buy are hardware like hooks and beads, or materials that are entirely new to flytying.. the sculpin heads, barred rubber legs, etc.
Saved some deer and elk hair from the animals my son hunted, so I'm good there ;-)
and all the pheasant feathers I'll ever need from my own hunting.
Salvage of fur & feathers found while hunting/fishing/hiking adds to the stockpile.

I need to replenish thread and hooks annually. So $50 to $100 in hooks, depending on if I buy bulk or at the local shop. But I have stockpiled so much tying material over the years I really don't need to buy anything. Of course I still do buy stuff. I really enjoy tying.

Typically I spend $250. + every year on tying materials. I tie ALOT of flies! Of course I tie all of my own, but I also tie a large percentage of the flies my brother uses. Plus I'm always developing new patterns for my fly tying books. On top of that, I have 3 young kids at home that tie their own flies, and a 4th that wants to learn. Most of my money goes to hooks and thread, but I have been spending a lot more money then usual the last couple of years replacing old materials with fresh stuff.

Funny thing is, for as much time as I spend on the water, pretty much every day April through October , I've only fished 3 fly patterns all year. Just lucky I guess
