The Duchess Petticoat . . .

 I tea stained the Valencienne lace trim for a nicer ivory color.

 I sewed this trim to the petticoat hem to cover the stitch line from sewing the horsehair in place.

This is 2 layers of silver silk tissue for the back section of the petticoat.  I think it needs another internal layer with more horsehair for support and structure.  I am using 3" white horsehair braid for the hems.  (Jenson kept sitting and posing when I was trying to photograph it on the form.)

This is the muslin of the gown with the tissue petticoat back piece pinned to the form.

 This is the muslin gown without the tissue petticoat underneath.
