Valley Forge is a leading brand name of American flag manufacturers. Valley Forge flags are made of cotton and have rich, vibrant colors that will last for many years. The heavyweight cotton fabric wears well and flies beautifully. In addition to cotton flags, Valley Forge also makes cotton bunting, which is made of 2x2 ply mercerized cotton. Bunting and flags are designed for indoor or outdoor use and are made of high-quality materials with carefully done stitching to prevent frays or premature aging. Outdoor flags include 4 rows of stitching and reinforced fly ends for durability.
