We live in a really old house (100+ years), and it has tons of lovely woodwork. Well, sort of lovely. The downstairs is stained and finished, but a little beat up (a maple-y color, I think..I'm not good with colors of wood), and the upstairs is painted white (was that way when we got here). We were pretty committed to not painting the downstairs trim when we moved in, but lately I really have a bug to do it, especially the stairs. It just feels so dark downstairs; the floor plan is not really an "open" one, and since we live in the city, we are REALLY close to the neighbors on either side and don't get a ton of natural light. I just feel like it would brighten things up a little bit.
I am inspired by the two pics above: first from Domino Mag and second from Pottery Barn. I really like the mix of the white and the natural wood for the stairs. I know in theory it's a shame to paint over wood, but I also feel like it is not as "wrong" as it used to be. Dan is warming up to the idea, so we'll see. :-) Hopefully no one else is gasping in horror.
