Above is the design for the character, showing were the armature I bought will go.
To then make the mould I first needed to make the character from Plasticine, I wrapped the armature in cling film first to prevent and Plasticine or foam getting into the joins of the armature.
This is what the finished Plasticine character looked like. I left the hands off, as I wanted to make them at a later date.
I then began to make a mould for it using clay. I made a flat bed of clay that covered half of my model and put a clay wall around it to prevent the plaster from running out.
The first part of my mould is now complete and ready for the plaster.
To make sure I got no air bubbles in in the plaster, I flicked it into the mould.
once the plaster had completely set, I removed the layer of clay, turned over the mould to repeat the process on the second half of the mould.
Once the plaster was dry, I removed all the plaster, and notice the split line of the mould. I gently opened up the mould to reveal my Plasticine model inside.
