For this project, a lifecasting of an arm is used as the armature for the Free Form® Sculpt.
Free Form® Sculpt is a 1:1 professional grade sculpting medium that is easy to use. Equal amounts of part A and part B are scooped out of the containers for mixing. Parts A & B are immersed in water for a few seconds. Free Form® Sculpt blends easily to a consistent neutral grey color; perfect for seeing details. The consistency of the Free Form® Sculpt allows for quick build up over the armature.
