For creating this stab wound, I had to first sculpt the wound out of clay. I then had to create the mould, so had to create a flashing (edge) for the would and then add the silicone. Next, I had to fill my mould with more silicone for the piece itself, I  also add softener and colour so it will look more realistic when applied. Once applied, the edges are blended out and the colouring added to create the finished look.
