Travelling on the Overground off peak presents an open vista for sketching as the carriages are not divided and passengers are seated opposite each other. From a sketchers perspective it is as if potential subjects are placed before you. The man in the hat noticed I was drawing him so I quickly switched to the feet of the people sitting next to him to his left. He was sitting opposite a woman who he occasionally spoke to, I assumed her to be his wife. When he got off a young woman replaced him, she was wearing a very short skirt in order to present her thigh tattoos. I was already engaged in the drawing of the woman in the striped top on her iphone seated further along the carriage. As I turned back to the spot opposite me to begin the next drawing I saw YiTing was now sitting there, she was a student of mine.
