I have a few things to work off of already.
Gray and white chevron fabric for the curtains. I bought this fabric for Kari's shower.
I have these posters from our trip to Wyoming this summer we want to put in the room too. I'm not sure on the color of frame and matting but I am thinking natural matte with either white (my vote) or dark wood (Tim's vote).
Here is the office that started my orange and gray obsession.
My walls are just about that color now. I am not planning on painting.
More inspiring rooms. Not all of them are offices...
