Yesterday I participated in Ali Edwards' day in the life project. I wanted to make it as simple as possible so I set the timer on my phone to go off every hour and I took one photo.
Then this morning I resized the photos to fit on on two 4x6 pages. I added a few notes in that extra space at the bottom: "not pictured--Clara playing in the rain. Eli throwing the football 50 times. Steak soft tacos. Thunderstorm, cancelled soccer game. New book Clara got in the mail." And done. Simple and documented!
