Hi - I have a 50's-era knotty pine room that I'd like to lighten to have a whitewashed appearance This is our compromise between adding needed light to the room and honoring the original design/materials. I know this is a mortal sin to some - we've spent three years 'sleeping on it' and can't come to love it. I'd like to have the walls be very light - creamy white - but still be able to faintly see knots and grain. Has anyone done this? Thoughts? Am I in need of a stain? A dye? Some kind of paint?
