Here is how I used my last skeleton. If you look closely you can see his large gold earring and two gold teeth. He's holding a rifle in his right hand and a beer stein in his left. His parrot, Jack, sits on his shoulder. The parrot is an oversized resin bird repainted in parrot-like colors. You kind of have to use your imagination to see "parrot" but, hey, don't you have to use your imagination to see a skeleton as a pirate? :-)
I didn't have any striped fabric that was just right so I painted the fabric for his shirt. I used the sleeve from one of hubby's worn out undershirts so it's really soft and worn. I'm guessing the pirate is much more comfortable with that piece of rope as a belt than around his neck like it was when I bought him, lol.
