I tried the surface technique Batu taught me yesterday and the piece comes close to doing what I want it to do. Still would like to experiment with a more amber-looking surface. I'll let you know when I get there.
Last month I was in New York and saw some amazing Chinese scholar rocks at the Metropolitan Museum of Art. I was surprised at how similar they looked to gingko trees I had seen earlier in the day on the street---bright yellow in their final glory before winter.
I haven't uploaded pictures of the scholar rocks yet but here are links to my new "Dormancy" sculpture. I would love to hear your thoughts about it.
