Creative advent calendars

Typically, every year for Christmas I buy one of those cheap advent calendars that has a small bite of waxy chocolate behind every day. This year, I want to try something different. I'm not sure if making it myself and eating each goody myself is a bit of a waste, but it still looks like such a treat. Eventually, I'd like to come up with a creative way of doing this for my children {when I have them}. I found this blog that had a few fun, creative ideas I'm considering now. I especially love the coffee travel cup one!
