A fly swap is a cool way to share some new patterns with other great fly-fisher(men and women). Each person ties a dozen of a designated category like; nymphs, musky flies, steelhead etc. Each of you mail your dozen patterns to me. I sort them out and in return you get a dozen assorted patterns from the other tiers. There are no fees other than shipping them to me and I will pay the return shipping on the envelopes.
