Each watercolour technique is examined in a separate chapter "Line and Wash", "Wet on Dry", "Wet and Wet" and "Combination Techniques" and each chapter has advice on materials, preparation, starting off, finishing off and common problems. There are detailed step-by-step instructions in the form of artstrips - each one hand painted by Paul Taggart himself - as well as sample projects for painting from a photograph and painting in the field for each method. There is also advice on colour mixing and general hints.
