We were lucky to get to play with the new Kaisercraft Documented papers this month for the ATDML Gallery and I made this cute 3" minibook. Nothing new in the design which is based on this template using a sheet of 12" cardstock and scoring at 3", 6" and 9" then cutting along the solid lines.
I folded each square along the dotted line alternating from folding under and over and then adhered some back to back to make pages, and some leaving open at the top to make pockets. I then made a cover to wrap around the book, four small tags for pages and decorated the book in the school themed papers adding stamping an washi tape for interest (without adding bulk)
