For the photos, Chapman recommends choosing simple images with a clear subject—think one or two people, not a crowd shot—so the banner doesn't look busy and hard to read. Then, select a few of the banner's cutout letters and trace each one onto a photo. Cut out the images and glue them to the letters. If you plan on keeping the banner long-term, use an acid-free adhesive, Chapman says.
