Hi Shopmom,
I have a jacquard from the 80's, Feux d'Artifice, (87, I think). Anyway, it's incredibly silky. I think the fabric feels softer and drapier than regular silk twill. I would almost buy all jacquard, if it were possible. It hangs beautifully and seems to glisten as the woven pattern catches the light.
Anyway, FWIW, I love mine.
