Loving this idea for wall art! My Parents still have a bunch of old barn wood and I know the perfect place for this look. You can find the "hello" sign (or one similar at least) and a lot of other cute stuff from Oh Dier Living.
Although not quite how I would imagine my own house, I am in complete AWE of the creativity and use of color used in designing this home! Just wish I could see more! Can't you just imagine the woman who lives here?!?
