What I really like about it...the little squares of paper have magnets on the back.
So when the holiday is over, you pull them off and they take no room to store.
And it can be used year after year.
Your Creative Juices also provides a free printable for the numbers, but since I have a black, white, and red theme this year I didn't want any pink. So I ended up make my own. You can print them off below. Or go over to her site and print off her cute numbers.
