Its pretty easy to make. Start with a double sided 12 x 12 sheet of two-sided cardstock (like SU has produced in the Spring Mini!). Fold the square in half vertically, then open the fold and fold it in half horizontally. Open the square and fold the bottom corners inward to the center. Fold the bottom half of the square up along the center folded line. Fold the panel in half with the diagonal pockets outside and glue the insides together. Whole punch/eyelets and then use fibers, ribbons or loose leaf binder rings to keep them all together.
