Decorate your own calendar
I have always wanted to make my own calendar using my photos and this morning I did, starting off with January 2010.
The large size would be the best to use for printing. You can adjust the size to fit on letter size during the printing process. With my new computer up and running, maybe a desktop calendar is next.
