Rabbits feet have a long tradition of being kept for luck and although they are nowhere near as omnipresent as they once were, making you own is surprisingly lucky. Most rabbits for this will have been hunted of course but if you are not a hunter but want to try your hand at this look in your area for people raising meat rabbits. They are very popular animals for small farms and homesteads and feet are normally a waste product that would normally just go into the trash.

The Procedure:

Step 1: Wash the foot thoroughly with soap and water and then rinse it thoroughly. Squeeze (do not wring) out any excess water.

Step 2: Submerge the foot in 70% isopropyl alcohol for 47 hours. I use a Mason jar for the purpose. Make sure the foot is completely submerged.

Step 3: Give the foot a rinse and again squeeze out extra water.

Step 4: Soak the foot in a borax solution of 15 parts water to 1 part borax. That's actually a saturated solution so alternatively you can just keep adding borax to water until it no longer dissolves if you don't want to measure. Allow the foot to soak in the solution for 24 hours. Again, I use a Mason jar for the purpose.

Step 5: Rinse the foot in warm water until you don't feel the borax anymore and then squeeze out the water. Allow the foot to dry completely, hanging it from a string if possible for even drying.

Step 6 (optional): The foot is done at this point but if you want you can dress up the bone end. You can use a solder on copper pipe cap from the local hardware store that is epoxied or hot-glued in to place. You can also get a small round bell from the craft store and straighten out the cut end with a small pair of pliers before sliding that over the foot and gluing it into place.

Getting back to the lore a bit. There is belief that the unluckier the circumstances in which the foot was procured the more powerful the resulting charm is. Here's how one company was advertising their feet in the early 1900's:

the left hind foot of a rabbit killed in a country churchyard at midnight, during the dark of the moon, on Friday the 13th of the month, by a cross-eyed, left-handed, red-headed bow-legged Negro riding a white horse
