After seeing this post on pinterest, I had to hide the wires under my desk. I had an extra curtain panel from the other side of the room. If are interested I found this at Walmart.
I then measured the length with a tape measure and cut the fabric with scissors. I then just nailed it to the wall.
If you are wondering this desk if a kitchen table from Kmart cut in half and mounted to the wall with a board underneath. I have always loved the desk but we have so many wires. We even put the wires in the wall so we do not see them from the tv. But they still went to the power strip.
I like this idea because we can still get to the wires if we need to change things in the future. I tried hiding the cords before but they would fall down or we would need to change something. This is our best option for now. This desk is in our bedroom and I never enjoyed seeing the cords.
