Creating an elf on the shelf is a fun and festive holiday tradition. To make your own elf on the shelf, you'll need some supplies: a small plush elf toy, a book on the rules and ideas for the elf's adventures, and some basic crafting supplies. First, decide on a name for your elf and make a name tag to attach to the elf's outfit. Then, pick a unique outfit for your elf to wear each night, such as a red and green outfit or a snowman costume. Next, create a list of fun and silly activities for your elf to do each day.
