Photo Calendar.

Check out this photastic DIY wall calender I found at photojojo.


The step by step directions (found here) include sweet little tips like this:

"For sheer indestructibility, you can laminate your photos. Nothing but the Dark Side of the Force will ever be able to harm them and they’ll pretty much last forever."

or this:

While their position in the calendar will shift throughout the year, these numbers will always line up on top of each other in a column.

* 1/8/15/22
* 2/9/16/23
* 3/10/17/24
* 4/11/18/25
* 5/12/19/26
* 6/13/20/27
* 7/14/21/28

(and if you laminate your photos you can write directly on them with dry erase markers instead of using sticky notes! or even use instant photos that don't need an extra lamination)
I can't wait to search for some numbers for my own calendar!
