A lucky rabbit's foot, while not at all lucky for the rabbit, can be just the good luck charm to keep you going. While many may find it is cruel to find and kill a rabbit strictly for this purpose, if you have a pet rabbit that has passed and want to preserve its memory in the form of a key chain, here is a guide for how to do it.
Cut the foot from the rabbit.
Use a sharp knife to pierce a small hole (big enough to fit your beaded chain through) in one end of the foot.
Soak the foot in a mixture of water and Borax.
After the foot dries, sew the wound with twine.
Run a beaded chain with a clasp through the hole. This chain will help you attach it to your key ring.
Give your rabbit's foot to a friend or someone in need. The superstition is that the rabbit's foot is only lucky for the person who receives it, not for the person who makes it.
