I used straw looking printed paper and used animal stickers surrounding the pictures.  In the lower right corner I took a picture of the book from the Authors visit that had been autographed by Tedd Arnold and just cut the barn out and attached it to the front of the barn sticker cutout.  Covering the sheep in the top right corner I again took a picture of the words in the book that was repeated all throughout the book.  Each of the kids in the class represented a farm animal in the book.
