I love making storyboards. I create one for almost every session I do because they are so fun to create. I usually use three of my favorite images and add a little saying at the bottom or a name or year. They end up being 10x20 inches and fit into a standard frame that usually comes with a mat for three 5x7s. You take the mat out to frame these wonderful storyboards.
Here's one I created for Kendall and her First Birthday Session.
