These curtains are of a beautiful, quality silk.  The dupioni weave give these a lustrous quality and a satisfying weight.  I purchased six panels in the biscotti color, and am very happy to find them as advertised.  They have a warm, lightly metallic gold color reminiscent of honey.  They are semi-opaque and make the grayest day seem warm and inviting when the light filters through them.  They arrived ahead of schedule and were carefully packed as well.
