How I square rough lumber

I need to make another piece of trim for the cherry built in, and thought this would be a good time to show how I square an edge on lumber that still has bark on it. In the pictures below, I've shown my method.
I've planed the piece down to my desired thickness. I've attached a piece of paneling to the top of my rough lumber using small finish nails. This will give me a straight edge to run along the fence of the table saw. Then, I've set the saw blade height to cut just through the rough lumber. By letting the paneling follow the fence, I end up with a straight edge on the rough lumber. Now I can work with a squared edge. This is my simple method of squaring rough lumber.
