Started going through my box figuring out what materials I need to get ready for the fly tying shows this fall and winter. I sold close to 300 flies during the shows last year. I figure six to seven flies from a bunch of yak hair. I can get 20 flies from a deer tail. Do the math. I need 50 packages of yak hair and 15 bunches of hair. Not to mention the crystal flash and hooks. I love to tie, but right now it seems pretty overwhelming.
