I you want to rusticate it take a look at this video.
And if you want to finish it completely here's a few simple steps. After you rusticate it give it a light coating of a tad of wood filler diluted in water to the consistency of skim milk. Let it day completely and buff off the excess. Black alcohol based stain will cover most sins so I recommend it. But first, apply a coat of red stain, let it dry and buff it. Then apply the black over the red and let it dry. The red underneath will make the black look richer. Give it a light buff. At this point you could stop but to really finish it off apply a light coat of button shillac, let dry and lightly buff. Good luck.
