Print and cut out the six pieces. Use a blunt needle or knitting-needle and a ruler to score the edges before folding. First glue together the individual pieces using the white flaps. Then glue the pieces together using the coloured flaps. When gluing together two pieces start with every second flap of the eight flaps and line each up carefully. The flaps shall be glued down on the front of the piece below. The last four flaps will now be easy to glue down.
