I used elm, cherry, or walnut depending on what I had in the fire wood pile that would turn. As for how I attached the antler handles, I fit the antler to the mug, then drilled a small hole into the antler and threaded a short piece of a twin fast (drywall) screw into the antler.cut off the screw head with my dremel, then spotted the mug with a fostner bit and filled the spot with clear expoxy and screwed the antler into the mug and waited for the expoy to set up. I then finished the mug with laquar. I have attached handles this way for over ten years and have not had a failure yet! The mugs are all of a size that a beer can will fit into them, which is useful for rendezvous.
