We got the lights at Lowes and TJ made the headboard out of a 10 foot board cut in half (to make 2 pieces the same length). We then stained, sealed, and attached it to the wall with some mounting hardware meant for picture frames. He also made the nightstands before we left Indiana. Luckily they survived the move.
Here's the before... we had some interesting off-white textured wallpaper to deal with. We took it down on one wall but decided to make the other our accent wall. The blue is Glidden "Rich Navy" and it took just 2 coats. Now it looks like navy blue textured wallpaper.
