3-way switches have long been the stumbling block of many homeowners. There are at least 5 different ways of "designing the electrical wiring layout".
Here is the basic design. A hot wire needs to start at one of the switches common point. A pair of wires called "runners" or "travellers" carry control between the switches. Finally, a control wire starts at the second switches common point and goes to the light. The light obviously has to have a grounded wire present to operate.
The light will come on or go off whenever either switch is flipped once.

This is my first attempt at a moving GFI. Please check back in the future to see any improvements!
