I have a number of gessoed panels for acrylic and oil painting, and decided to try sumi ink on one. It was really compatible! While the ink is wet, you can smear or lighten it, or let it run in interesting patterns. I noticed, though, that it never became completely resistant to rubbing off, so it got sprayed with acrylic varnish to make sure it doesn't smear. 8" x 8", with some Inktense pencil.
