Mold the pottery clay into the shape of a werewolf nose. Pottery clay is the best clay to use because it drys hard, and it falls apart when dipped in water. This is very important for the later steps. Make sure your mold is perfect and precise in all details. Let it dry.
Coat the mold thinly with liquid latex with an old paintbrush. The liquid latex will ruin the paintbrush, so make sure you don't want it anymore. Let it dry for 10 minutes. You can use a hairdryer to save time.
Add several more layers of liquid latex, allowing each layer to dry before adding the next.
Peel off the latex. If this is difficult, dip it into the bowl of water. It will not damage the latex, but the clay will slip right off.
Paint the nose in shades of brown, beige, black, and yellow with latex paint.
Apply it to your face using latex glue for skin.
