While they're a bit twee, I have a weakness for Snow & Graham. And I just picked up this calendar at my local paper store.
(I don't think I ever bought a calendar this early before. I hope I remember it at the end of the year. Someone remind me, okay?)
This accordion calendar folds down to just 3.5 x 2.5 inches, but when opened in all its glory this little guy is 30 inches long! We like to call it the micro wall calendar. The accordion calendar allows you to see all of 2011 in one view and 12 unique S&G designs, too.
