I used two sided Jillibean paper but you just cut a 7" x 4 1/4" out.
Slide it on to you cutter length wise and score at 1" and 4 1/4".
The score the long sides at 1/2".
Next cut out the four corners alos the score lines.
Round all the corners.
Folder and stick together with scor tape.
Hope it helps.
