Thanks Nichola, I needed a laugh!! :-)
At the risk of sounding terribly boring and serious, my chapters also focus on case studies, and my sup has said to bring them to life by telling them 'as a story'. Find the hook, the big main theme/finding, then start off with this as a teaser in the intro then build up the evidence to the final exciting conclusion! In reality, the chapters are still really linear and descriptive, but am trying to make them interesting. I also include some analysis as I'm going, relating what I'm finding back to the literature, then the discussion chapter will do this to summarise the whole thing. This might not be applicable to your work tho.
OK, back to today's exciting story!
