"Tying Material Is Expensive"
I hear you there! They can put a heavy burden on the old wallet.
I still take about 20 minutes to tie a fly myself, but they are getting better and better looking.
I have found a few patterns that I use often and have been practicing with only them. That way I have a sort of specialty in my fishing AND tying so I can get better at a few skills and then add a fly or two at a time once I am profficient with the ones I have.
Just a suggestion, Good luck!
