Recently I did some work for 'Bloomsbury Publishing' on the new 'River Cottage Handbook' on Sea Fishing that basicaly involved drawing diagrammatic illustrations of fishing tackle, rigs, and knots . The real challenge was to create images that are simple enough to be read easily, leaving enough room for annotations, making the colour flat so that it can be changed to suit the chapter by the designer and, most importantly, creating drawings of very simple even mundane objects like fishing line and making them interesting enough to pull readers in.
