I have more duck feathers than I can use, so send a sase and you can have some for free. Please send ziploc bags for the material. What you can expect...
duck flank: about one or 2 small ziplock bags, like you would get from a flyshop for $3. If you really use alot I can give you more.
goose feathers (brown) (not biots ) I have a ton of these, can give you like 10 feathers.
white goose feathers (not biots ) I can give like 2 of these.

Things I would appreciate if you have extra:
white goose biots.
marabou the color for alevin.
olive wire in size thin

If you live in Chico you can cruise over to pick them up and save yourself the postage, or arrange to meet on the feather.
