Laurie from 2Peas (laulley) shared this great template to make a 20x24 poster of a year in photos. Here's my 2008 POTD poster. It was a lot of fun to go back through my year in photos. (I did cheat a little; I missed three days of posts in July. I debated whether to leave the spot blank with just a number for the date, then decided to use a photo from the closest date that I posted more than one photo in a post.)
I'm going to try it again for 2009 but do it as I go this time instead of doing the whole year at once.
