Shutterfly has a variety of iPhone cases (for all models) which can be customized with your Disney photos. If you are anything like the residents of the cottage, you will have LOADS of images to choose from. If you're not really the type to take lots of photos while at the parks, consider purchasing the PhotoPass images. You will not only get the images of your family, but you can purchase the entire package of photos from your trip and, bonus, you will get some stock images too. Our images included some seasonal shots, so we could remember how the parks looked during our October stay. Easy-peasey.
I made this case in less than 15 minutes. Mr. Photos From The Parks snapped this image during Mickey's Not So Scary Halloween Party several years ago. I love it! I added my own text, and poof! My very own iPhone case. The cost was about $55.00, so this isn't necessarily a project I would do for all the members of our travel party (we usually knock around Walt Disney World with upwards of 17 people), but it is perfect for that Disney fan who has everything.
Until next time, may all your days be filled with fairy dust!
