This is a very easy Elf on the Shelf exit idea. Tonight, while your kids are sleeping, take a picture of your Elf on the Shelf saying goodbye to them.
We used our smartphone to take a picture with the front and rear facing cameras at the same. Since we have two elves, one took the photo, while the other one said goodbye.
If you have one elf, you can just take a picture of the Elf on the Shelf saying goodbye. We put this photo on my daughter’s iPad. When she wakes up Christmas morning, she will see the picture. You can also print out the photo and put it by the Christmas tree.
