Please note: Burke Decor does not accept wallpaper returns at this time. Why? Wallpaper is produced in batches (similar to tile) and due to dye-lot variations that occur based on when the rolls are produced, we are unable to accept returns. We accept and offer free shipping on all wallpaper exchanges for all wallpaper that has remained unopened.
