I just wanted to share with all of you a great solution for messy cables that not only are unsightly in the living room and bedroom but also are potentially dangerous for curious little kids (like mine) and nosy pets.
I discovered a decorative cable cover called D-Line at HomeDepot.com about two weeks ago that miraculously conceals cables. The great thing is that it is super easy to use (clips on and sticks to the wall) and can also be painted to match your wall/baseboards/floor. Here's the link for the D-Line on Home Depot.
I attached before and after pictures so you can see for yourself!
