Here, metal shims have been inserted into the sculptures to define how the molds will split into two parts for each paw. Clay keys and screwdriver slots -- in reverse -- are added to the shims, and the non-sculpture surfaces are given a coating of vaseline so the ultracal will not adhere to them.

The upper surface wil be molded first, then the whole assembly flipped over and the bottoms of the paws finished up.
