Bug Holes!
Gah! Today was an interesting day. It began with the de-molding of the second Elizabeth. She had many large bug holes (air holes) on her surface.
So, I did some research on how to eliminate bug holes. Found a great discussion on sculpture.net. I am going to try using a product you add to cement to reduce the air content (Fritz Pack Air Minus) and packing the cement mix instead on vibrating it.
