So, I went over to Zazzle.com After someone mentioned on the etsy forums that they now have shoes available for you to customize and create!
After looking around at all the cool products available to put images on, I signed up and created a postage stamp using our Octo-Girl monster card! How very cool. I'm thinking it will be great fun to order some, and send a letter to grandma with our new, customized postage stamp upon it!
Here's my Zazzle gallery (not much as of yet, only the stamp, but there will be more in the coming weeks)
