Clarke & Clarke Breegan Jane Xan Caribbean Wallpaper. Xan is a modern take on a seagrass wallpaper, this smart vinyl is beautifully complimentary to so many designs in the Breegan Jane collaboration yet equally as strong and alluring in its own composition. Relaxed yet textured, mellow yet robust, Xan engages in the senses and elevates interiors with its luxurious feel.
