CaMillion is a UV-resistant bonded polyester sewing thread color-matched to Sunbrella fabrics, made for stitching outdoor awning and marine canvas. The bonded polyester construction resists ultraviolet degradation, mildew, and weather so seams hold up to prolonged sun and moisture exposure. Recommended for sewing awnings, canopies, boat tops, covers, and cushions in Sunbrella and similar acrylic fabrics. Available in a range of thread sizes and stock colors and sold per spool.
