Sunbrella binding is durable, fade resistant and mildew resistant for a long-lasting, color-rich binding. Lengthwise edges are woven to minimize fraying. Centerfold binding folds naturally in the center for easy installation. Works well around corners. Simply fold the binding around a fabric edge and sew in place.
