Whether it's for making a decoration for Halloween or a model for science class, making a skull can come in handy. If you need to make multiple skulls, though, you'll need to make a mould of the skull. This allows you to make as many skulls as you want. This process takes a few days to do correctly..

Skill level:

Things you need

  • Skull
  • Non-drying clay
  • 1-inch paint brush
  • Cheesecloth
  • Scissors
  • Utility knife
  • Mold builder latex

  1. 1

    Plug up any holes in the skull using the non-drying clay, filling in the seam at the top of the skull if necessary, as well as any cavities for the eyes or the nose, which will prevent cracking later on when you're making the actual skulls from the mould.

  2. 2

    Apply a thin coat of mould builder latex to the surface of the skull, working around the entire area. Let the latex dry completely, then apply another two layers of latex using the paint brush. Make sure to apply the latex all around the skull.

  3. 3

    Cut squares out of the cheesecloth in approximately six-inch-by-six-inch squares using the scissors. Apply a layer of latex to the surface of the skull using the painter's brush, then put on a layer of the cheesecloth, making sure to form the cheesecloth against the skull as tightly as possible. Let the latex dry. Continue alternating layers of latex with layers of cheesecloth until there are eight to10 total layers. Allow the latex to dry completely before proceeding.

  4. 4

    Cut a vertical seam up the back of the skull using the utility knife. Peel the mould off the skull. It is now ready for use.

Tips and warnings

  • Find a non-drying clay that's any colour other than white. This way, you'll be able to see the contrasting colour, letting you know if you need to fill in any other parts as well.
