We post lots of tips for keeping your cables organized, but like most cleaning tasks, this one is best dealt with using multiple solutions. Combine our favorite DIY cable management techniques below and keep your cables organized and untangled for good, without spending a dime.
1. Bread Ties
Use bread tags to identify what each of your cables are for. You can even go as far as printing labels for the tags with a label maker, though writing on them with Sharpies works just fine, too.
2. Bike Tubes
Small portions of old bike tubes work much better than rubber bands for holding excess cable wire. Larger mountain bike tubes work a little better for this, but road bike tubes work fine, too. Chop up the tubes that have been punctured a few too many times to ride.
3. Binder Clips
Use binder clips at the edge of your workspace to keep cables from slipping away when your devices are unplugged. You don't have to use black ones--get colorful clips or silver clips to match your decor at places like Target.
4. Artwork
If cables still need to cross your desk, try hiding them with some propped up pieces of art and framed photos. This one will also save your walls from holes!
5. Use Color
In addition to labels, we also like to use different colored cables for different devices, like Jucies, a successfully funded Kickstarter which should soon be available as a purchasable solution. Color-coding is such a fast and easy way to visually distinguish a mess of cables. You can buy colorful cables for areas like your home theater for next to nothing at MonoPrice, or dye them yourself using this guide.

I used my Brother label maker to tag all of my cords (especially chargers) so I know what they are when I pull them out of the drawer.
I love the binder clip idea. Even when the cords are plugged into your device, they'll keep the cords draped orderly.
I crochet cotton yarn around mine. They don't tangle anymore, and I can do them to match other things.
Thank you for these great ideas - I'll be trying the bread and binder clips!
I use black hair ties to wrap around my electrical wires. I also use my label maker to label what product the adapter is for when I get home. If you make it twice as long it will stick to itself and pretty much stay for the duration.
All of these ideas are wonderful for organization of a few cables and I have incorporated some under my desk but what if you live with geek? Then there are many, many more cables. I developed a ziplock bag and duck tape organization system that works like a charm for keeping track of all the cables not currently in use but still "needed"! Check it out here. It has with stood the test of time. My husband can actually find the cable he needs now!
I was dealing with really messy TV cables and I used a tip I found on Apartment Therapy to fix them up. I wrapped them with yarn and am totally in love with them now :)
