Bug's Book was Winnie the Pooh and Mickey Mouse themed made the same way:
For our Disney trip this year, I decided we had enough little books lining the shelves. I debated several ideas, finally settling on the one suggested by my friend Jenni - pillowcases.
Several people (including cast members!) asked me where I bought the cool pillowcases.
Then I had the kids put their own autograph and year on the other wide edge. We had the characters sign with Crayola brand fabric markers. We tried to make the fabric taut using cardboard and rubberbands, then cardboard and knots. Finally we settled on cardboard and chip clips!
Here's [one of] the final product[s].
