I saw the idea for this here: http://thecraftingchicks.com/2011/05/summer-fun-chart-and-photo-journal.html. But I have seen similar ideas other places in past years. I didn't use her download, but it is free if you want to use it. I decided to do my own thing and instead of printing it poster size from somewhere I just printed it on an 8.5 x 11 at home. I don't know if we will really do ALL of these things this year, but it gives us some fun ideas.
