    Coat the cardboard with wallpaper glue or white glue.


    Cover it with an aluminium foil (glossy side facing up) and glue it by expelling the air bubbles from the centre toward the edges.


    Dry it with the cardboard side upwards and weights to keep the cardboard flat.


    Once dry, return it and cut along the edges to take of all the overlapping aluminium parts.
