Rich in texture and neutral in color, a rug woven of sea grass, like this ivory-bordered one, offers endless versatility. Because sea grass is durable and even somewhat stain-resistant, it's perfect for use in high-traffic areas. What's more, sea grass is fast-growing and easy to harvest, making it an eco-friendly choice. Use it alone to add warmth and texture to a space, or layer it with an antique rug for an exotic look. A polypropylene backing adds durability and helps to hold the rug in place.
