Plenty of Planking
However subtle, stripes provide the organizing feature of this casual living room. Planking on the walls and ceiling mimics the planking in the rug, which also acts as a cohesive element for the neutrals and blues in the rest of the room. Beach-inspired accents -- a painting, a seashell-filled lamp, even ribbons on the edges of bowls -- reinforce the aesthetic without overpowering the space. A clever furniture arrangement creates an entryway, while a consistent color palette joins the two separate-but-same areas.
