I used two different colored safety eyes. One brown one for his regular eye and one black one for the shot out eye. I used red puffy paint for the blood around his shot out eye. I sewed his mouth by pulling yarn through the back and around the front where I wanted it to be and then putting the yarn back inside. I just tied it in a knot and called it good. For his hair I used longer pieces of yarn for the top and filled in the rest by sewing it in.
For the mask I crocheted a piece that would fit around his head. I brushed it out to give it the fur effect. I drew a template of the bunny face and then cut it out of felt. I glued the eyes, teeth, and nose/forehead piece to the base. I painted it with silver metallic paint and added details and dimension with chalk pastels.
