Outline the viewing port. For now, leave the top of the box open as you make the spectrum. This port needs to be drawn on the outside of the box. First, set the CD or DVD on one side of the box, half of an inch away from the left edge. Use your pen or marker to trace the circle in the middle of the disc. Put the disk aside for now. Then, get your paper tube, and center it over the circle you traced. Trace the inner part of the paper tube.Now, move the tube over half an inch, and trace the inner part of it again.These circles will tell you where to cut the box to make the viewing port.The two overlapping circles will look like an oval.
