With all the tech in our homes these days, we usually have plenty of extra cords and cables lying around the house. Sometimes we’re just too lazy to properly wrap a cord up when we’re done with it, throwing it into a drawer or plastic bin. Pretty soon that box of wires can become one disorganized mess. Here’s a quick simple how-to that will keep your big box of cables neat, manageable, and tangle-free.
Here's what your tech pile might look like.
1. Place one end of the cord in your palm, with the rest of the cord hanging over the back of your hand.
2. Begin to wrap the cord around your hand.
3. After winding up about 2/3 of the cord, squeeze it with your hand and pinch the middle of it.
4. Take the remainder of the cord with your opposite hand and tightly wrap it around the pinched area until you have a couple inches of cord left. Pull the very end of the cord through the loop.

And you’re done!

This method is a bad idea. This will almost definitely put tension on the cable and connectors and cause it to wear prematurely. It may look better than a pile of spaghetti, but I cringe anytime I see a cable wrapped like this. Google "over under cable wrap", do what the pro's do. If you want it to stay together use a cable tie of some sort (I recommend velcro)
over under method is good for thicker instrument cables that have those built in velcro things. i like this method for smaller thiner cables, like usb an earphones, because you dont need a clasp. and it unravels without knots.
Over-undering is a must for thicker cables or delicate cables. As silentfool said, it reduces wear on the cables, increasing the life of cables. However, I find it much more useful when dealing with long power cords, or other thick cables. If your old extension cords won't lay flat, it's likely because they were wrapped incorrectly in the past. Over-undering is easy to learn and, once you get the hang of it, is fast. Even if you use part of the cable to secure the loop, over-undering the rest of the cable will help dramatically.

I find any method that takes too long to unwrap or wrap back up doesn't get used in my house. So i just keep a baggy of tons of cushioned twist ties in my boxes of electronics storage, and keep all my wires straight that way. Super easy and fast.
The key to this method is to have a LOT of twist ties, since they can get lost easily, and you won't use them if you have to search for them. So better to have lots on hand in an easy to reach spot, and suddenly they're more convenient than trying to tie the cable with itself.
