I think this would be the closest I ever will come to make a tutorial...

This is some shots I took while I was making the plaster holder for the silicone mould of the Chavant sculpture
It is to be used to make a foam-latex stop motion puppet

Description:
1.1-1.2: I started with building a clay border around the silicone mould, and also made a border over the back and tail, so that it will be in 3 parts.
1.3: I spread a thin layer of plaster, covering every part of the side I'm going to plaster at the moment. Then I just make the layer thicker.
1.4: I put in some thick steel wire to reinforce and make it more durable.
1.5-1.7: I follow now with two more layers of plaster, with a layer of plaster bandage as more reinforcement.

2.1-2.4: when starting on the other side, I first took away the clay separation line, and put a layer of Vaseline on the plaster. then I made the same procedure as on the first side of the mould. making sure that the plaster don't get over to the other side

3.1-3.3: And the same gos for the front of the mould. First of with the clay, Vaseline, and then fill it with plaster.
When the plaster had hardened I used a knife to carve the edges so that the thin line between the part show.

I have not taken them apart jet, because it has to harden a bit more.
