Step 3 Folding the Crease Pattern

Examine the lines on the paper: the black, solid lines are mountain folds, the red, dashed lines are valley folds. (For those unclear on the distinction.) I tend to fold all the mountain folds first and then the valley folds. I also tend to fold the valleys as mountains and then reverse them, but that is to taste. Any way you can get the creases going in the right direction is cool.
