Have you heard of Photoboother? It's a cool website that turns your photos into an old school photo strip. Once you've uploaded your photos (four frames per strip), you can email it to friends, order prints, or download the file and print it out yourself.
I used photos from Emily and Colby's Marfa, Texas wedding for this test, below. Wouldn't it be cute to include photo strips in your thank-you notes to wedding guests? What fun things would you do with them?
