The ink in an Edding mapping pen (01) was sufficiently dense to cover the drawing made with a Uni Pin 0.05 pen (which, incidentally, got completely used up making this work). The paper is imitation Japanese tissue, inexpensive and good for experiments and tracing, and wrinkles very slightly and delightfully where the marks are dense.
So the wanderings of last week have now gone ...
I also liked the tonality of the notebook sketch, so for the first time I tried out some traditional mark-making using lots of cross-hatching together with the cartoon-style lines I normally use. It's interesting! - quite a range of tone resulted, I like the ghostly effect of the lighter forms against the dark.
As I worked I was also thinking of some of my larger drawings with used a dark background, like Before There Were Saturdays. It's important to me right now to create the background with pen rather than painting in a black background, which would have been a lot faster, but wouldn't have had the same movement.
