When rolling up an extension cord, first stretch out the cord completely. Then, take the plug-in end and walk it back to the other plug in end. So now the cord is in half. Then start at the plug-in end and pull the rest of the cord to you in a circle... When you get to the "loop" at the end, wrap it two times around the middle of the circle and slip the "loop" part through the hole at the top of the circle. You can then hang the extension cord from this loop!
