Slap a badly-designed coat-of-arms on a piece of cloth, then add the name of the entity right above it because the coat-of-arms is obscure and no-one would recognize it (which is the main function of both flags and coat of arms). A flag like that just screams "the entity I represent has no right to exist, we'd be much happier as a British/French/Spanish/German/Burkina-Fasoan colony"
