Make a first bob in clay, and put it into fresh plaster!
Once it's dry, make the top part and unmould carrefully:
Don't forget the head!!
Prepare the armature with well placed magnet
Be sure it does fit in the mould!
Put a lot of silicon and press strongly:
Once it's dry, open carrefully:
Don't forget the head!!
And make as many Bob as you want!
