To make this shape, begin by drawing a line vertically towards the top of the paper. Next, draw a line diagonally to the right and down. From there, continue the line in a vertical movement toward the top of the page. You should have a "N" shape drawn now.

From the upper left corner of the box, which is where the pen should be, draw a diagonal line towards the upper right until you reach the midsection of the box. Then, continue your motion diagonally down and to the right, creating a roof on the box.
Next, draw a diagonal line to the left and down. This completes the "X" shape in the middle of the box.
