With only rare exceptions, I've tied all my own flies for around 35 years.
While I'll experiment, I was never into tying for fun. It was just what I had to do to have the flies I needed.
I still tie on the Thompson vise I bought in the mid-80's to replace my original Herter's and still use most of the same tools too.
I have a several lifetimes worth of accumulated materials and I'm painfully aware of the stuff that I never should have bought or collected in the first place.
Nowadaze I only purchase what I absolutely need
, and make do with what have or what I can scrounge.
And I like it that way.
