Ice is the answer!!! Most 2 part molds use modeling clay to block out half the mould with keys (bumps or some kind of shapes to help line up the 2 halves of the mold). The problem with this method is the faces are made out of clay and I don't want to ruin the work I've put into these. So ice!!! Freeze off half of the mold and hope the plaster will set before the ice melts. 😅
