Never underestimate the power of cable management, fo' real. No really though. I don't have any good before shots of our wall mounted TV cable situation, but it was wildly similar to this hot mess here:
JUST KIDDING. But not really.
We didn't have the knowledge nor the balls to really start putting holes in the wall and threading all the wires through, the way I would have liked. So we took a look around Home Depot and came home with what we figured was the best solution - tubing that conceals your hot mess and sticks to surfaces! Not quite magic, but it'll suffice. The tubing was white, so I painted them with leftover wall paint once in place. I am ok with the final result.
