Cut a length of ribbon to serve as the drawstring for your bag. Then, thread it through one of the drawstring holes, and work it around to the other side. Continue to tug on the ribbon until it is even on both sides. Then, finish by tying a knot at each end to prevent the ribbon from slipping back through the holes.
Tip: To make this step easier, untwist a metal coat hanger; tie the ribbon around one end; and use it to guide the ribbon through.
