Yesterday, I ran a sketchcrawl in Dulwich Village with Urban Sketchers London. I also found time to draw across four pages of my concertina sketchbook, and the results are shown below. The paper was initially prepared with torn paper collage, acrylic gesso and random marks with diluted indian ink. Then I drew on location with chinagraph pencil, which is a waxy, quite thick black pencil which encourages a bold approach. I am finding that the concertina format encourages a more flexible use of different images across the spread, developing a portrait of the place, in this case Dulwich Picture Gallery and its surrounds.
