In a small outdoor space, an outdoor rug can play multiple roles, creating a seating “island” as it does here, adding color and style, and making the area appear larger thanks to the introduction of an overall pattern. Designer Annastasia Mitchell chose this rug carefully for its seafoam blue color, which repeats the apartment’s interior color palette, “providing a sense of visual flow,” she says, and to repeat the horizontal pattern of the louvered windows.
