When I was growing up, we had one at my grandma's house, but it was more of a "permanent" one. It was made of felt and had little pockets at the bottom and a felt christmas tree at the top. In the pockets were little items. Some were little felt cutouts, like a present, and others were little mini ornaments, like a nutcracker. Each day, one of them got pinned onto the Christmas tree. The last one, that you put up on the 24th was a little sleigh and reindeer. Me and my brothers and cousins always argued about whose turn it was to pin that day's item up on the calendar. In fact, now that I think about it, I think my grandma still uses it, but since we're all grown up and none of us live close to her, she pins all of them up unless one of us makes a day trip down there. After looking, I found one on Amazon that is fairly similar.
