The calendar consists 31 ATCs, bound together with a Bind It All, and mounted on a collapsible cardboard frame. I also included a little costumed rat, to keep her company.
The back cover folds up to create a triangular stand for the pages. Each day in October, she can flip one over as Halloween approaches. I used playing cards for the bases of the ATCs. They're just the right size, and it's easy to quickly cover them with scrapbook paper and then cut them out. I didn't cover the backs because I don't mind the way they look, and the cards would be way too fat with all that extra paper involved.
Here's the calendar on October 1:

I really had fun making a card for every day of October. Here are all the cards before they were bound:
