Paint sides of box and lid in the colour of your choice.
Paint X's one colour and O's a different colour.
Allow paint to dry.
Cut white card to the size of the lid and glue in place.
Divide box lid into thirds and glue strips of coloured card in place to make playing grid.
Store the playing pieces in the box until ready to play
For a change, use different cutouts like cars and boats in place of the traditional noughts and crosses or for a miniature set use novelty buttons with the shanks removed so they will sit flat on the board.
