To keep the knob in place You will need a nut (as shown) on EACH SIDE of your lumber.
Here is what the finished product will look like.
To hang, I found a stud, drilled a pilot hole and screwed directly through the board into the wall stud. You will need to screw in another screw as well opposite of the other one to keep the board level. I just painted over the screws because I like a rustic look but if you don't want to see them, use finishing nails instead of screws, countersink them in the wood, fill and paint.
|You probably noticed that I changed the board cover. You can't go to all of this trouble and then not have it match, right? So it did end up costing $7 in the end but that's not a budget breaker.|
