Elf on a shelf is a fun and creative holiday tradition! It involves placing an elf doll or figurine in a new spot each day, and each morning the elf reports back to Santa Claus on whether the children in the house have been good or bad. You can get creative with the elf's placement, from hanging from a chandelier to perched on the edge of a shelf. The goal is to spark excitement and imagination in the children, while also keeping them on their best behavior.
