This was a fiddly (for me) box to paint, using different colour lustres plus gold. The 4 blocks of gold are visible if you look and in "real" life they stand out nicely. The bottom of the box has been painted the same as the lid and looks quite stunning on a low table in my lounge.
After the lustre had been applied, I outlined the lustre colours with black pen work and also with a fine brush to make a thicker line in places for variety. There is gold around the edge of the top of the box, and around the edge of the top of the bottom of the box.
Does that make sense?
I have a square sort of unpainted box that is about 4" by 4" which would look stunning using this method.
