Question #2 - tail on beaver skin and tan

I am wanting to mount a hooped beaver hide with tail attached
I am thinking that if you want the tail to lay nice and flat with clean, natural edges that you need to open from the bottom and sew a form up inside (?). Every one I've seen, the tail just doesn't look great.
Also, would you skin tail separate and sew back on or leave all as one piece? I'm wondering if the tail would tan up the same as the hide or if it needs a different approach?
Also would appreciate any photos if anyone has done one.

Or, we could talk politics LOL

I've had several beaver hides tanned by Moyles with a tail on them, I just split the tail and left the top half on and shaved it down
came back from them fine, if it had a curl in it I would just spritz it with a fine mist of water on the shaved side and put a heavy block on it to take the curl out.

You can't tan beaver tails unless split though, they have to much gristle and oil inside of them to do so !
