Next, obtain a cardboard box that is more than a foot wide and a foot long (this one came from the Kroger Store), a foot long ruler, a sharpie type pen, and a scissors. If you do not want the dark lines in the butterfly cage use a pencil. Mark a dot in the middle of the box and place the 6 inch mark on the ruler on the dot. Draw 6 lines through the center to make 14 wedges. Draw lines from the tip to tip of each wedge to make an outer circle. Cut the disk out and repeat to make two disks.
