Thanks for the comments. I was really fortunate to have a piece of ivory that big to work with. Man was I nervous when I drilled it and turned it. And I pieced together the stopper out of two pieces, with a little ebony band in between, because I didn't have a piece of ivory long enough for a one piece stopper. Doubt I'll ever make another solid ivory call. So, it was a treat, but I'm glad it's over.
