Once you have cut out your first section, place this paper plate on top of the second plate and trace around the inside of the cutout portion onto the other plate. Now rotate your cut plate about 1/3 of the way around and trace out the section again. Rotate the top plate another 1/3 and trace out the section one more time onto the uncut plate. The uncut plate should now have three, equal sections traced onto it. Make sure there is enough space between each section so the plate will hold together once you cut them out. Cut out each of the sections that you just traced onto the plate.
You should now have two paper plates, one with a single section and another with three cut out sections, as shown. Take the plate with three sections and tape a different color of cellophane onto the back of each opening. Make sure to trim your cellophane so that it does not extend over more than one opening.
Punch a small hole through the center of each plate with your pencil
