custom blend of annie sloan Coco and Old Ochre and highlighted with both clear and dark waxes Try 8 parts coco and 2 parts old ochre. Random blobs of silver metallic paint brushed with clear wax. When dry "pounce" dark wax and brush in one direction.
And here it is after layers and layers of paint were added. No sanding involved. I used a clear wax, dark wax on top of the various paint colours. Some of the colours were custom, but the layers began by using Aries and Barcelona Orange.
