What about the first bird down on top and the second bird down on the bottom?
Put the bases of the birds fans together so they make a circle. Find something to cover the base with, a piece of leather cut like a large concho or something like that and put a hole in the middle of it.
Take some leather thong material and hang your spurs, beard, and each shell from each opposite side of the big concho.
cut down your shells if you have them and a bit of hot glue and the leather thong can hold in the beard into the bottom of the shell so you see a bit of the shell and the brass.
PM me and we can talk.
