The "cover" is just chipboard (cardboard!) that is cut 8.5" square. I'm working at covering that. All the inside pages vary.... I didn't have as many *cool* papers as Ali does over on her blog, but we were creative & worked with what we had on hand. We cut some papers 6x8.5... others an even square, we used a 6" square vellum envelope, a 6x6 scrapbook insert, assorted design papers cut in different widths & heights and even cut up a baseball card file keeper. I'm excited to see it all come together. I love it that it doesn't have to be perfect. So I'm writing in my daytimer to pull out the photo printer and get it SET UP (yes... it's still packed with more boxes than I will ever admit!!) the week before December. We'll be printing our photos often!! If you're going to play along and work on a book, please post a link in the comments -- I'd love to see your progression as well.
