Method :
1. Mark
the cardboard strip (a) into four sections, each 7.5 cm (3 in.) wide.
Fold the marked sections into a box shape and hold it with
tape. |
 |

2. To make a bottom piece, place the box onto the large
piece of cardboard strip (c) and trace around the edge. Cut out the
shape. Tape the bottom in place. |
3. To make top or lid for the box, place the bottom piece cut out, again on the remaining cardboard strip (c) and mark with the pencil around. Cut just outside
the lines you drew, making a top shape slightly larger than the bottom
shape. |

4. To make the sides of the top, place the top shape at the left
end of the long narrow strip (b). Draw a line along
the right side of the square. Mark four equal sections of the same size
on the strip and trim off the small section remaining at the end.
