If you have drawn pictures of creatures and monsters, it's only natural to wish that you could see them in real life. Your creations may never be alive, but you can reproduce them in three dimensions by turning them into a latex masks. These masks are not difficult to make, and once you have created a mould you can produce many masks out of it. With a little work you can create an entire army of your creations.
Cut a styrofoam head in down the middle, separating the face half from the back half.
Set the face half on a work table.
Sculpt the face you have drawn onto the styrofoam face with water-based clay. First rough out the clay with your fingers, then use sculpting tools to refine it and add details. Occasionally spray the clay with a little water to keep it from drying out.
Spray the finished clay face with two thin coats of acrylic enamel spray to seal it, then with two thin coats of dulling spray to keep the plaster from beading up.
Mix a small batch of plaster according to the instructions on the package.
Brush a thin coat of plaster onto the entire clay face with a paintbrush. Really work the plaster into the nooks and crannies. This is called the beauty coat because it captures all of the detail that you have sculpted. It should be about a quarter-inch thick.
Allow the beauty coat to dry; see plaster instructions for how long this will take.
Mix a larger batch of plaster and let it sit until it thickens to a peanut butter consistency.
Spread the thick plaster onto the beauty coat, creating a mould that is at least an inch thick.
Let the plaster dry.
Dig the clay out of the plaster mould. Only use your fingers and wooden tools to reduce the risk of scratching the plaster. The various sprays will help the clay separate from the plaster.
Fill the plaster mould with liquid latex all the way to the brim. Cover it with a sheet of cling film.
Let the latex sit for an hour to allow some of the ammonia in the latex to absorb into the plaster, forming a skin against the mould.
Pour the excess latex back into its container.
Allow the latex in the mould to fully dry, then peel the mask out.
Cut out eye and mouth holes in the mask with a sharp pair of scissors.
Paint the mask with latex paints and stretch a string across the back to hold it onto your head.
