~Cutting Snowflakes: A classic that gets your kids imagination flowing. When you finish cutting them maybe add some color or even glitter to make them sparkle and hang them in the kids room.
~Handprints: Theres many recipes out there for making molds. You could press the hands of your kids into these molds to make an adorable momentum for your tree. Again painting them after they've baked is fun too. :)
~Decorating Stockings: Make the stockings you hang above the fireplace more personal by adding some fabric paint or anything else the kids think of adding.
