Halloween Countdown block calendar

A couple weeks ago I got together with my sister-in-laws and we made these block calendars to countdown to Halloween and mine's finally finished!  You can find the instructions HERE.  My sister-in-law Jackie did hers a little different and I love them too:

I've started one for Christmas, and I can't wait to make a birthday one too!  Though that one might need 3 blocks because kids start counting down to their birthdays months in advance...
