I've been collecting my guineas' feathers cuz my niece wants to decorate a wreath with them. What's a good way to clean all the wood shavings, etc. off them without damaging them? (I don't pick up the really filthy ones.) I thought about sewing them into a pillow case and washing them, but the stuff would stay in the pillowcase also. Needless to say, I want to do this the lazy person's way. Thanks for any ideas!
