I beleive there is a link to the place that i got the materials to make the molds In my thread, It is called Algesafe, it is a skin safe flexable mold, you simply dip your hand in and hold it there for the time it takes to cure, once it is cured it will be super strong Jello i donk know how to explain it, but it will flex enough for you to pull your hand out, you have to be carefull if you are gonna have fingers up though you need to cast in something strong so when you demold they don't break off, Plaster is what i used to cast but you may want to use something stronger, these molds are are only good for one cast because you simply cut away the mold to get the cast out.
