CREATURE CASTING: Monster Foot Tutorial

by Egg Sisters Cosplay

As featured in the current issue of Cosplay Culture Magazine, the awesome Egg Sisters show you start to finish how to cast and mold to make the perfect cosplay creature extremities for your projects.

In the first video, they demonstrate methods to make a foot cast with multiple layers of duct tape, sculpting with clay over the cast, then detailing and texturing the clay.

Part 2 shows the process for making a three-part Mold of the Foot, using UltraCal 30 molding material.

In Part 3, the foot is cast with Creature Cast Liquid Rubber, then excess trimmed and sanded down.

And last and but not least, the steps for painting are shown, and Toenails are created from foam.
