If you have a friend to help you, you can make a plaster mask instead of either of these options.
Since the Mick Thomson mask has a tall, exaggerated jaw, use a sheet of foil that extends past your chin to give yourself more room to work with.
Cut a flat line high above the forehead. If you don’t have long hair like Mick Thomson, you might want to use a more rounded line around your forehead. Cut the mask into two pieces. Cut the foil in half along the upper lip. This gives you more control over the shape of each section.
You can use homemade papier mâché instead, but plaster cloth is usually easier to work with and less messy.
Cool or room temperature water is recommended, since warm water may make the plaster cloth stiffen up faster.
If the strip is drying out before it is smooth, add a dab more water with your fingertips. If water is pooling on your mask, soak it up with a paper towel. Try to use less water for the next strip, since the plaster can wash away and become less effective. If the cloth rips or leaves loose strings, cut the fray off.
Mick Thomson has gone through several mask designs. Pick your favorite and use reference pictures of that model, or you might confuse yourself looking at multiple different designs.
Optionally, you can mix streaks of grey paint into the silver to make a “grittier,” less shiny mask.
