Valley fold the top third down
Valley fold the top third down, so that you have a rectangle made of 6 squares.
Create two folds, one diagonal valley fold (from left bottom to top right) through the middle of the center square on the third you just folded last, and one diagonal mountain through the right square (from left top to right bottom).
Look closely at this picture. You will fold a valley fold through the center square, and a mountain fold through the right square. The are diagonal folds, going in opposite directions. Completing these folds will require valley folding the right third of the paper.
To accomplish these two folds easily, stick your finger under the third that was folded down, under the rightmost square. Fold the center square in half diagonally, so that the left squares fold over.
To accomplish this, stick your finger under the first fold, on the right side, and and create the valley fold diagonally through the middle square.
