They are right in my line of sight when I am sitting on my couch. It's annoying. I give them the evil eye every time I sit down. I finally got off my butt and did something about it! I purchased a pack of 3M clear hooks. The smaller you can find the better.
I attached three of them in alternating directions on the back of the table leg, then hooked the cords around them. (The little tab to remove them was long and stuck out the side of the table, so I just folded it over and tucked it in with the cords and it fit perfectly.)
Such a neat and cheap trick, but makes a big difference!
