I give them away, sell a few and mostly I fish them. Most of my tying is for upcoming outings and I usually tie up the regular producers on that piece of water, but then I'll tie up a couple of new ones, just to try them out.
When I tie at shows and such I always give my flies to those who have patiently sat and watched and listened to my ramblings. I'm surprised at how many tiers at shows don't give out the flies they've tied. Some sell them, and some just don't share. To each their own I guess.
