This will deal with how to manage electrical cords or cables of the sort that get piled up behind your computer desk, audio/video center and cords that you want to store. first off you don't want to manage cords that are fragile or non-flexible in this manner because you could damage the wires inside. but for the right sort of cord (one that can fold back on itself easily) this works well. Another benefit to this technique is that your cords don't end up twisted as they do when coiled.
Step 1: Begin
First untangle the cord and fold it into two equal sizes
Step 2: Repeat
continue to fold cord into smaller and smaller halves, when it is about 8 inches to a foot and a half (depending on preference and size of cord) take the two ends and make a simple through the loop knot.
Step 3: Enjoy
Now the cord is much less of a mess and can be made long again in seconds with minimal tangling.
