1) Clean with a mild bleach solution and consider repainting depending on the shutters' condition.
2) Hinge the shutters together to span the desired length for your wall hanging. I wanted my shutters to afford our queen-size bed a more substantial-looking headboard, so I had my husband attach 4 medium width panels and 2 small width panels together.
3) Drill pilot holes in wall, and using anchors, screw in all four corners. You'll need to add more screws in the middle of the wall hanging if you want it flush. Otherwise, leaving it loose in the middle will achieve a more multi-dimensional look (almost like there is a window behind the slightly ajar shutters).
