I would totally do it, might be kinda fun to dye em like the old school keychains, but I really don't know how to preserve 'em! Just been coyote food thus far.
I made some years ago.. buried em in Borax for a few weeks then set them in a shotshell with epoxy similar to a turkey beard. Then my wife threw em out saying they were creepy lol
Those sound super cool. I might have to give that a shot. Christmas ornaments for everyone. Bahahaha that's hilarious about the wife tossing 'em though.
