To start the tradition of Elf on the Shelf, you will need a special Elf on the Shelf doll, which can be purchased at most toy stores or online. Once you have the doll, you will need to name it and give it a unique personality. Some popular names include Buddy, Jingle, or Sugarplum. You will then need to explain the rules of Elf on the Shelf to your family or friends, which include that the elf will watch over everyone and report back to Santa each night, and that the elf should not be touched or it will lose its magic.
