From many years ago, these are some of my pen and ink drawings of canines. My eyes were better then; the ink dots are super-fine. These were a lot of fun to do, but the stippling was intense.
The great thing about pen and ink is its portability. A minimum amount of supplies is my favorite way to play with art. All that I need is a fine point pen, my drawing on bristol board, a clipboard and paper to support and protect the drawing.
