Step 1: Supplies
Hot wire carving tools
paint brush / old tooth brush
Step 2: Make the Face
I have a set of hot wire carving tools, but I only used one tool for this project. The Freehand Router tool. You can change the wire shape on this tool to accommodate your sculpting.
I had this nice piece of blue foam left over from a older project, it was about the right size to cover most of my torso.
I carved the evil face and sloped out the edges making sure to carve many deep grooves all over the surface. When finished, I spray glued it to the cover of my book. The shell of the book is 3 cardboard panels duct taped together.
