Flashcard Advent Calendar

I don't know about you, but this year we are excited to get the Christmas decorations out.  I am planning on the traditional day after Thanksgiving decorating activities.

I have a couple of advent calendars that we use every year, but I think I might make one that is a countdown for when we leave for Arizona.  I like this idea from Country Living and I think I might have all of the materials already, which is a big plus:

And I love the little ornaments that are hanging from each flashcard.  The kids can take them off each day and hang them on the tree.

Do you have an advent calendar that you traditionally use or do you like to create something different each year?
