Print out all of the images and text that you plan to add to your display board.
Place the foam board on a table with the paper side down. Use the measuring tape to measure the long edge. Place a pencil mark one-third and two-thirds of the way down the edge. Make matching marks down the opposite side.
Use the pencil and the yardstick to make two straight lines connecting the points on the opposite sides.
Use the box cutter to carefully cut the foam along the liens you drew. Do not cut all the way through, since you want to leave the paper backing intact.
Tape your images and printed pages onto the display board. Avoid placing anything over the cuts, since this will prevent the display board from being opened.
Stand your display board up and bend it at the cuts so it will stand on its own.
