Well after reading Morgan's post in this topic:

Now why didn't I think of that? After reading his post I realized that he is right in that I really don't paint wood any different then any thing else. I just paint what I see. But, I suppose it is easy to say that the hard part is learning to see and know how much detail to put in or leave out. So I guess we could answer all questions about how to paint anything with one word. "Practice"
