I found I really got my teeth into this exercise and kept adding to it over a number of weeks. Once I had this topic as a focus I kept seeing lines everywhere, although it was sometimes a challenge to get an interesting composition. The images included were taken at the Olympic park and the University of York. As with many of the other exercises I found it so illuminating to really think about what I was looking at, to follow a trail of clues that might lead me to the subject matter I sought.
