I need to have a translucent material for the forthcoming play. I'll be making 4' W x ~8' tall flats. I will have back lights on the flats so that the light (and the painted colors) will be seen. I was thinking about using organza or light weight muslin. I've seen scrim material for sale - but it is way wider than I need and a bit too expensive. Would organza work? Does anyone have any other inexpensive alternatives? The fabric needs to be "opaque" until it is back lit.
