- Start from
- Locate the two tiles (forming a 90 degrees, valley fold, angle) located in the top-left of the picture
- Temporarily deform the configuration in order to flatten the angle between these two tiles,
this allows to fold them 180 degrees backward
- They both become flaps and the final shape can be obtained by returning the other tiles in ther
original position
