American flags presented in Arlington National Cemetery are completely made in the United States. The fabric, thread, and all component parts have to be manufactured and produced in the United States, along with many other items purchased by the Department of Defense. Early American flags were made from wool, cotton, linen or silk, depending on the availability of materials and the intended use. The most common method for assembling the American flag throughout history has been sewing pieces of dyed and undyed fabric together and then sewing or embroidering the stars onto the blue material. Designs can also be printed onto flags. This detailed image was captured by @arlingtonmedia.
