These are a super cute way to show your kids “evidence” that Santa was here!! These wood Santa, elf and reindeer prints are sold as a set or individually. Made from 1/8 Inch thick wood and can be used year after year!! Do not get them wet. It is wood and can warp if put in water. I used flour for the pictures. But anything can be used. Baby powder and even spray snow from your local craft store. They work well on both carpet and hardwood floor if using flour.
