There is a beautiful willow towards the end of Sequim Bay Road that I have tried to paint a few times. This is an attempt in sumi ink, on a very old piece of Asian printmaking paper - not sure which kind. I wanted to really emphasize the willow, so tried the Inktense pencils on just it...
I had the paper and even a sumi brush for years, but incredibly, never tried them with sumi ink. I LOVE this medium.
