I don't really like to paint whole houses. I remember painting some for people when I was in my "single mom" days. I also painted a 57 chevy for the body shop guy in lieu of deductible for insurance when I had a car accident.You do what you have to!
But I do like to paint portions of a house; such as a window, porch or an entry way with a door like this one.That way I am not stressing out about perfection of perspective drawing and no rulers are involved. I really do hate to measure things.I like the intimacy of the close up view.
