Can't Remember Where Your "Elf on a Shelf" Has Been? Try This! by Linda Klonsky
If your kids are like mine, they may adore that lovable Elf On a Shelf. But if you're like me, you may be having trouble remembering where the little guy has been every day, or you may be afraid of duplicating its hiding place. I solved this problem by taking a picture of it with my smartphone every day. I refer to the photos when I need to hide the elf and I upload the pictures to a folder on my computer. I figure it may help me next year when I have to hide the little imp again!
