I made this card protector for a poker player:
It is about 4 cm (1,6 inches) across, and is made with a glas orb placed on a bottle cap as a base. To give it proper weight and stability.
I wrapped the orb and the cap in plaster bandages, and later on sculptured the face with paper clay. The teeth and the eyes are made with polymer clay though.
It seems to be working out as a card protector, since the poker player wants two more of them.
