One way to coil the extension cord is to hold one hand up and separate the thumb and fingers. Use the V shape between the thumb and fingers to hold the extension cord. You can go around your elbow with each loop but not to tightly or you will not be able to get the extension cord off. I've seen people make larger loops by taking the other hand and holding it outstretched to their side for each loop; that way each loop is the same length but longer than going around the elbow. After you finish winding the extension cord leave enough cord to tie a loose knot to keep the extension cord from unwinding and getting tangled up. This way is simple and fast.
