Here is what makes this handcrafted, all-weather, Flag so special: Construction begins with quality material made of DuPont SolarMax� brand nylon that flies smoothly in the lightest breeze. The starfield is fully embroidered. All seams are a full 1/4" turn and sewn with color matched thread. For strength all stitching is in one direction, from header to fly hem, chain stitching for all horizontal seams, and a lock stitch for all edge hems. Fly hems are finished with four rows of lock stitching and a 102 stitch "X-box" reinforcement at the top and bottom of all flags up to 6' X 10'. Flags 8' X 12' and larger feature an "X-box" reinforcement and each horizontal seam.Heavy duty nine ounce material is used for the header, the strongest in the industry. Flags up to 6' X 10'feature heavy duty brass grommets. Flags 8' X 12' and larger feature heavy duty chrome D-rings for maximum flying strength.
