Here's how to make it:
Cut cardstock to 11-1/2 x 5-3/4. Cut two additional pieces of cardstock to 3 x 5
Larger piece of cardstock-Score (with the 11-1/2 edge at the top) at 3", 3-1/2", 8" and 8-1/2". Fold on score lines.
Smaller piece of cardstock-Score at every 1/2". Accordion fold on score lines.
The following picture should give you the idea
Next you'll attach the accordion pieces to either side of the folios front edge.
Attach the other side of the accordion piece to the back of the folio. This will make your accordion pocket for your five cards to fit into.
