 The first such opportunity was advertised in Circuit Noize magazine in 1997– simple gold lame flags of 3 feet by 5 feet that came with a matching bag.Flags can be of almost any fabric, but silk, organza and lamé are preponderant, with silk being the most favored.Silk flags are usually dyed in vibrant, ultraviolet fluorescent colors, creating an almost hypnotic spectacle when spun rhythmically.
