You can just paint the trim and leave doors and cabinets stained, but this look is better with paneled doors than hollow core doors. I used two coats of Zinsser 123 and two coats of a latex acrylic enamel.

You may leave some areas not painted. Look at older homes from the early 1900s and earlier, and you will see stained trim in some rooms and painted in others.

Hear are some examples of mixing white trim with wood:

You just don’t close the windows until the paint is dry in Canada oil based paint is no loger available and IMO you should use latex ot acrylic for thisto avoid the stink of oil paint.
