This is an interesting way to display beards. My father and I do something a little similar, though it allows you to display spurs too. It works both with or without spurs. Our method is, use a torch to separate the plastic casing from the used shotgun shell and keep the cap. Use a drill to drill out the primer on the shotgun cap. Run some sort of string (we use leather strips) through the cap and thread your spurs onto it, and return the string through the hole. Tie a knot to hold it all in place. Then use hot glue to further hold it in place as well as glue the beard inside of the cap. You can then hang them on anything, nails on the wall, deer antlers, or thread them onto an arrow and hang them with a coat rack or something similar. I don't have any pictures or video of the process, but here's what they look like finished:
