I finished working on this today by adding some embellishments of gold and copper gutta. These were diluted with water then splattered from a paintbrush onto the silk. I had previously dyed the scarf using microwave fix dyes. I blended yellow and red on damp silk to produce a range of yellows, golds and oranges with a hint of pink.
It was warm enough to work in the garden and leave the scarf to dry in the sun.
