This video tutorial is in the Arts & Crafts category which will show you how to tie a decorative Door Knocker knot. Take a piece of rope and make a loop at the center with the left hand end of the rope over the right hand end. Now pass the right end above and through the loop to make a half knot. Twist the loop to make a figure of eight, pass the right hand end through the lower loop of the "8" and back through the upper loop. Repeat this once again. Now repeat these steps with the left hand end of the rope and tighten both ends to complete the knot.
