I tried to surprise my wife by painting the wall in the living room but surprised myself even more because all I can see are vertical lines. Do you have a photo of your finished product? I'd like to know what to expect before I go and buy my 3rd gallon of paint. I didn't know what I was getting into before I started this. One persons comments said they had to brush the last coat on (x's) can this be done with a roller? How wide a roller?
