I love the many options that electronics offer me, but I DO NOT like all of the cords and mess that goes with it. I chose a small secretary style desk for our home computer and I really like it, because it fits our needs perfectly. However, it did not have anything in the back to hide the cords (or the cute red heads).
I went to a fabric store and got simple black fabric, hemmed it, and attached it to the desk with craft/fabric Velcro. I still have very easy access to all of the cords, but I don't have to see them when I don't want to. I liked the result so much, that I did the same thing for our small entertainment/TV stand.
