Do steps #7-10 on the other side of the paper so that you
have creases that are in the places where the red lines are.
12.
Fold the paper at a diagonal so that there are triangles
above the newly folded crease.
13.
Unfold the paper. You will now see a crease going
diagonally across the paper (*a green pen has been used to distinctively
show)
14.
Do the former 2 steps so that there are 2 diagonals that
intersect each other at the center. Both green and black lines are for
mountain folds while red lines are for valley folds.
