6"X 6" Derwent Wash Pencils Paper This was the first time that I have used my new Derwent Wash Pencils. You draw as regular and use a wet paint brush with water to spread and diffuse the graphite as a wash. I have a light, medium and dark pencil. It was a great deal of fun! The marigolds are the last from my garden and I put them in my Vaseline glass vase for display.
