Finish the other two sides (East and West) to complete the set.
Each set of stretches and folds consists of 4 folds: one each at the North, South, East, and West sides. Wet your hands with a little water to prevent sticking, and then lift one side (North) of the dough with two hands. Stretch the dough up high enough just so that you can fold it completely over to the other side of the dough. Rotate the bowl 180° and do the other side (South). Finish the other two sides (East and West) to complete the set. Let the dough rest for 30 minutes, covered, between sets.
