2. A Door Appears December 1st
Another way to introduce Elf on the Shelf to your family is to craft a tiny elf door and have little Jolly or Sven sitting next to it, ready with a letter from Santa. The letter can explain how the elf came over to keep an eye on the kids as the countdown to Christmas begins, and - voila! - you have a new tradition!
