Materials
There are several methods of making fake body parts. The method you choose is determined by the end result you want, your budget and the amount of effort you want to invest. Among many choices, your most basic options are;
1. Plaster. Quick and dirty, no real expertise is needed. Home level.
2. Latex, slip. For a rubber part, much more involved but the results might be worth it. Haunted house level quality. For people
who have had previous experience.
3. Silicone. For ultra-realistic fake body parts. Very expensive. Motion Picture quality. Not for beginners.
Important Note: You will have great difficulty learning these techniques without previous experience, books, videos or someone to coach you. Please get our video "Skins for Dummies and Other Props" and other reference materials.
In terms of a pattern you basically have two options.
1. Life-cast. Very realistic, but sometimes not as dramatic. Extreme details right down to finger-prints, but more costly and risky.
2. Sculpture. Limited by your skill as an artist. Can be as large and dramatic as you want. Takes more sculpting time.
NOTE: We carry most of the materials for these procedures. Please plan to spend some time reading the various articles at our site for much more information.

4. Fill with liquid latex, let it sit until a skin is formed on the inside surface of the mold. Mold release is not needed when using latex to plaster.
5. Dump out the "middle" latex back into its container. Let the latex that is stuck on the inside of the mold dry completely, which may take a few days. You may repeat the process if you want to make the skin thicker.
6. Powder the latex with corn starch before removing it.

Please budget time and materials for experimentation. You will not get this right on the first time. This is fun but can't be described as "Easy" like most of the stuff you get at stores these days. If you don't have artistic or craft ability please get someone to help you. Doing your homework will pay off, please invest in the books or videos as these things can't be explained in email nor over the phone. There is no single book or video that explains all these techniques in one place. You will have to adapt procedures and processes, but the basic principles won't change. If you are a little bit impatient, sloppy, or slow you will have extra expenses, frustration and disappointments. All techniques can be mastered with time, materials and patience.
