Step 2:  Fold it ver  cally from the centre and                                 Half   1
                              unfold.                                                                      2
                                                                                                      (1 part out of 2)


                    Step 3:  Fold it ver  cally into 3 parts and unfold.



                                                                  1                                               2

                    Step 4:  Fold it ver  cally from the centre fi rst. Then, fold again horizontally. Then unfold
                              both the folds.
