Molding your hand

So as promised I will be posting more often!  This time I am going to show you how I sculpted my hand appliances for my Kerrigan costume.  So the first thing we need is a copy of our (your) hand to sculpt on.  This allows having a prosthetic that fits your hand perfectly.  To do this we need a couple of things:
   1. Prosthetic grade alginate
   2. Some sort of container to put your hand in (like Tupperware)
   3. Plaster of Paris, Hydrostone, or HydroCal (preferred)
      3a.  A metal whisk or some other mixing tool you wouldn't mind throwing away.
   4. Shellac or mold soap and warm water

Now I could explain this all day long but I figured I would show the video that helped me a ton in this, and many other, processes. They very clearly explain everything and have a good quality video so you see what is going on.  The video is done by Brick in the yard Mold Supply and their webstore http://brickintheyard.com/ is where I get all of my mold making supplies.
