Break the paint at the door stop molding (the stop is the strip of wood the door hits when it closes). Standing in the bathroom you are painting with the door ajar, paint every part of the door you can see. If the door opens out, you paint the hinge side and the panel facing the bathroom. The casing, jamb and stop are painted right up to where the door will touch. If the door swings towards you, you paint the edge of the door with the knob latch in it and the panel facing you when closed. Paint the casing and jamb onto the stop where the door touches it and break the color on that outside corner. Hope this helps!
