This video shows how to make and use this simple, effective contraption. Please leave a comment if you would like this page to be expanded with more complete instructions and illustrations. The contraption shown in the video and pictures has two hooks. You could add more hooks if you would like. It is important that they be placed so that the cord lengths and tension are identical. For three hooks, the hooks should be placed equidistant from each other at the points of an equilateral triangle. For four hooks, the hooks should be at the corners of a square. See the main article about cord-making.
