Here is the third companion video to the Second Edition of The Prop Building Guidebook: For Theater, Film, and TV. It is a quick demonstration of whipping a rope. We usually whip a thin cord around the end of a thicker piece of rope to keep it from fraying. You can also whip the handle of a knife or ax (or similar implement) to add a bit of decoration.
You can see all the companion videos at the Prop Building Guidebook website.
