To create a banner, all you have to do is download the letters here, then print them onto cardstock and cut out with scissors. I had mine printed at my local copy and print center, but you could print them at home as well. To create a banner, the options are wide open. You could punch small holes on the upper corners and string them onto a ribbon or some twine. You could also attach the letters together with brads like I've done here on this birthday banner:
You can play around with the size a little bit, too, depending on how big you print the letters. I printed the Welcome Summer letters at 3" wide and the Happy Birthday letters at 5" wide. Both sizes printed perfectly. I love the festive feeling the confetti dots give these banners. They're perfect for all you summer decorating and entertaining! As a bonus, I included a simple invitation printable in coordinating colors that would be perfect for inviting friends and neighbors over for a pool party or End of Summer get-together.
