If you look closely, you can see how each pocket has the different pattern papers interlocking one another. When the book is put together, the papers overlap and create these unique pockets.
This is such a fun project and I only used two 12" x 12" pieces of paper for the inside pockets and an additional piece of cardstock for the covers. The flowers were made from scraps of paper and each is different from the previous flower. I loved making each of them. So, if you get a chance, check out Following the Paper Trail...you'll love what you see.
