I don't think you can go far wrong by purchasing or better still been given (if you know some shooters) natural materials to include:
[LIST][*]Pheasant tails[*]Hares mask [*]Mole patch[*]Rabbit skin[*]Deer hair/ bucktail[*]Partridge skin[*]Peacock Herl[/LIST]Should make a reasonable start for you. I have always found natural materials make the more productive flies....then again perhaps I just fish them more

. Add some wool, threads and tinsels to your list and your good to go. Hope you enjoy tying, its a good way of filling the winter nights.
