1) Take an A4 sheet of sugar paper (paper is too thin and card is too thick) and fold it in half length wise and then open the sheet back out.


2) Fold each side into the centre line you just made and then open back out.


3) Fold in half width wise and then open back out.


4) Fold the sides into the centre and then fold the corners such that their edge meets the first line.


5) Fold the centre back so that it is flush with the corners and place your fingers underneath the flaps. Gently pull and the box will open out.
