Re: cheap and effective fly tying
As mentioned in another thread IF YOU KNOW ANY HUNTERS, or if you hunt yourself...
It's that time of year... pheasant, grouse, chukar, partridge, ducks, geese, deer, elk. All have fine materials and if you learn what to pluck/cut and how to process them properly, you can get a good supply of materials to help you tie.
If you don't know how to process them, there are a lot of posts here on 'preserving materials' and on 'cleaning materials'. It's critical to learn how to properly process and clean materials to make sure they're bug-free, and to "tag and bag" them and freeze them until you learn what else to do with them.
And don't go overboard on stuff you're not sure what to do with. You don't need whole skins, but a few pairs of wings from ducks/geese/pheasants/turkeys, a few tail clumps from pheasants/turkeys, a couple of patches of deer/elk, and a good selection of flank and body feathers form various ducks, like mallards, teal, wood, widgeon, gadwall would be VERY useful.
You might not be able to offer them flies in trade just yet, but a bottle of their favorite booze or a few cigars (if they smoke 'em) will be cheaper than a lot of these materials would be.
