With the eyepieces done I move on to sculpting the mask in clay.
I place the two eyepieces onto the face form and start adding plasticene, which I've warmed in the microwave oven to soften it.
I build the beak up to where I think it should be. I'm not concerned about getting it smooth at this stage. I just want to get the proper proportions.
I use my clay tool to remove a layer of plasticene at the bottom of the beak, where the leather will lie over the resin.
And I cut off what will become the resin beak, and prepare to make an RTV silicone rubber mold of it.
