Remember when the kids were small and the countdown to Christmas was eased by an advent calendar filled with chocolates and little gifts? Give the concept a collegiate twist - with advent calendar pockets sporting the university mascot and stocked with coffee gift cards, pizza cash and sweet treats - and it becomes the perfect cheery treat to tuck in a care package or chase away the final exam blues. You can do the whole 24 day countdown, or just count down the days of finals week. Either way, this quick and easy DIY craft adds holiday cheer to any dorm room wall. Here's how to do it and what to tuck inside.
