Shantung usually has a hand like taffeta but has minor slubs, not the big ones you see in Dupioni. And according to Sally Queen it IS a period fabric! "Pongee" is what they called shantung in the Victorian era. If I remember rightly from Sally's book it was used for dresses after 1830. So I'm actually going to use it for my Poe Mourning dress and maybe as contrast trim, petticoats or ruffles on Victorian stuff.
