These are classic, and beautiful. I'd ask you how you do it, but that's like asking a magician how he just pulled a rabbit from your ear. You just gotta go on faith and appreciate the magic of it all in this life.
We used to find all sorts of bones in the woods, and they often ended up in our living room. Bones, feathers, sticks, rocks, you name it, it's collectible. The joys of woods work. And as you've shown, very artistic in their own right, and lending to even more in creative art.
Have you ever done a gallery showing of these? That would be cool. Your new tooth art is awesome. Reminds me of a floating door in space I would rather not venture into.
