This quilted nylon fabric was designed by myself and manufactured in Los Angeles, after searching for this type of fabric online without any luck. The ripstop nylon is strong, durable, yet lightweight -- perfect for totes, overnight bags, or even a doggy vest harness. It is urethane coated, making it water resistant.The diamond within this pattern measures 3 inches x 3 inches. I also have a smaller version in my other listing, which measures 2 inches x 2 inches. Happy Creating!
