you can get them there I have seen them at the Disney store or you can just make something up. I saw on the Disney site that they now have books and one side is for a pic and the other side for the autograph, they looked pretty cool!. We use a fat sharpee marker and 2 thick rubber bands to hold the pages open,one on each page. when we are done with the autograph and turn the page we tuck it under the rubber band. Saves alot of time flipping thru the pages each time and really helps the Characters too
We have used the autograph books, and as the kids got older we have done T shirts, pillowcases and a canvas bag-with a fabric marker. They were nice keepsake items that you could use!!!
We've taken our Disney storybooks for the characters to autograph so that when back at home and reading them at bedtime, the kids were able to remember how much fun they had on their trip.
