How to build a moving jaw
Using the classic elastic strap method, I am demonstrating how to build a moving jaw with one of my bases. The base I'm using is my new feline fursuit head, but this will also work with my classic style and kemono style bases.
To prepare your base for mounting onto a balaclava, line it with fleece fabric (or your preferred black, stretchy fabric) first. Then attach the eyes. either line the sockets with more fleece (for flat eyes) and glue the eyes to the fleece, or for 3D eyes, simply pop them into the sockets and glue the back once you're happy with the alignment. see https://youtu.be/RLtnJPVtL4M for more information on how to do this.
