Bob - I know JW does something similar to what krabbiepatty was saying (gluing the beards in the shell casings) and he may have a picture. I was thinking about doing this as well. They make some really nice wood display pieces to showcase beard collections. Some of them run pretty high ($$$) but if you're handy with tools, I'd be willing to bet you could look at a few examples and make something real nice for yourself.
krabbiepatty - I'd be interested in seeing what you come up with to showcase your shell casings and beards - when you do it.
