This video shows expert instructors tying a tie in the full Windsor knot. First you cross the wide end of the tie over the narrow end. After that you put the wide end up through the loop (behind the narrow end) and then you pull it through the tie. Next you cross the wide end behind the narrow end of the tie and then pull it back over the loop. Then you cross the wide end in front of the narrow end, go up the loop around your neck, and then down through the loop in the tie. You have now tied the Windsor knot.
