But, Mathspig prefers the paper cube designed by Phillip Stromberg of the Netherlands.His cube calendar (below) comes inside one of these paper cubes. This was a very spooky calendar as Mathspig could see her life disappearing in front of her eyes for one whole year. ARrrrgh!

Here is the way to fold a Phillip Stromberg cube:

Mathspig Cube 2.1

Step 1: Draw up a grid on cardboard 7 x 6 square.

Mathspig used 8 cm squares on paper. Cardboard would make a stronger cube.

Step 2: Count of squares and draw this pattern.
