Take your facial measurements. Measure the distance from the top of your ear to the middle of your nose; this will determine the length of the sides. Now measure the distance from one of your temples to the other; this will be the width.
Draw the outline of the 3D glasses on a piece of heavy cardstock. Cardboard will be too heavy, but regular computer printer paper will be too flimsy. The best paper will be cardstock, available at office supply stores.
Cut the outline of the glasses from the cardstock. Cut the glasses frame from the cardstock using scissors; the entire frame should be one piece (the ear pieces will simply be folded back to go over your ears). Using a razor blade or hobby knife, carefully cut out the eye openings.
Cut the blue and red cellophane down to 1 1/2- to 2-inch squares (colored cellophane will be available in large sheets at art supply stores). The squares should be bigger than the actual eye openings on the frame to have a surface to apply glue.
Glue the cellophane squares to the back of the cardstock frame. Apply a thin layer of glue all the way around the edge of the eye openings. Glue the red square on what will be the left side of the glasses, and the blue cellophane on the right side.
