So, you now have boards. Hopefully they have some character to them. Some imperfections and discolorations. That is what will give your wall personality. This part is not exactly a must do, but I did it. I took a measuring tape, and measured out 103″(the length of the wall), then started laying out the boards so I could get a sense of where I wanted each of the boards to go. That way I could avoid all the dark boards in one area and all the light boards in another.
