Well I had to start sometime. I pick up a skull today for 3 bucks and the first thing I did was cut the lower jaw off. I remove some of the teeth and then re-hot glue the jaw back on so the jaw would be open. I did not have latex but I found waterproof Elmer's glue. I mix it with the cotton balls and started to apply as needed. It’s now drying and will work on it more tomorrow.
