This is a kokoshnik a traditional russian headdress I created to go with my pseudo-russian baroque gown ([link]
Pattern, sewing and photography by me.
It's made from dark green satin with a small rhombus pattern. The top trim is a dark brown feather boa, bottom trim is brown elastic lace with a floral pattern. The cameo was originally on the package of a soap.
It has got lacing in the back to fit any head size and black cotton as lining. Between satin and cotton I used a fabric similar to buckram for stability. In German it is called Stramin, used for embroidery and most importantly it is a lot easier to get than buckram (actually in any tailor's shop).
