Stick-On Sickness

Use round “garage-sale” stickers to stick on faces, hands and arms to represent sickness.   You can use just the red ones, or be really silly and use red, blue, yellow and green.   They work great for any story where a character has leprosy, including Moses, Naaman, Jesus healing the 10 lepers, etc.   They also peel right off, which makes them easy to use when the character is “healed.”
