I love using sumi ink and metallic stuff. So when I saw an artist colleague @jimitick, who specializes in sumi ink enso drawings, using gold sumi ink on his Instagram posts, I asked him about it.

I've been using metallic leaf with Japanese Nihonga techniques but need more practice. I also want to explore other leafing/gilding techniques. Recently I learned a new technique for applying metal leaf from Solange Roberdeau at ink.paper.plate in Point Reyes Station out in West Marin here in northern California. I loved that she learned this technique from Robert Kushner while working for him--and that he suggested she teach these workshops. She now teaches this course all over including in my old home Santa Fe June 13; register online. Contact her on Facebook or Instagram for other locations and dates. Solange took this photo of us working on our art pieces in her Contemporary Gilding class.
Here's what I made that day:
