In Michigan selling parts of harvested animals is illegal BUT selling craft items made from harvested animals is just fine. Wrap a piece of felt around them so they can tied on to a quiver, etc. and now they're craft items! For a while, selling full length wild turkey feathers was illegal, but it seems they've lightened up (or perhaps been enlightened) 'cause now it's OK. It was always OK to sell chopped feathers 'cause they were craft items. The key is to add some labor to the item so it's not just taken from the animal and sold. I suspect that the craft loophole would work anywhere. Not sure, just a guess.
