When you are returning flies to the swapmeister, how do you usually do it? I put them in an Altoids-type (with foam glued into it) tin, in a small padded envelope (self-addressed and stamped), then both go into a larger padded envelope with the meister's name and my return address. Usually costs about a buck each for the envelopes, plus postage. Anyone have a better (read: cheaper) way to do this with the same fly-safety?

Thanks
