organdie

Organdie or organdy is a very light, thin fabric woven from tightly twisted cotton yarns.  It appears to be transparent and usually has a permanent, crisp, starched finish.  Although some stiffening treatments can be washed out, organdie can withstand repeated laundering and only needs to be ironed to bring back its original crispness.  Organza is a pure silk fabric which resembles organdie.  Organzine is a fine, folded, slightly twisted, filament silk yarn commonly used as warp to weave silk fabrics.  See organzine.
