As I continue to enjoy and explore the mysteries of the medium of watercolour, I've become a collector of books on the subject, trying to extract as much information as I can from a variety of sources in an effort to understand and improve what I do. Few books have come as close to a complete and comprehensive 'course' as this one does - insightful, explanatory, graphic. It's an good companion to Hazel Harrison's "Encyclopedia of Watercolour Techniques". Also unlike most books, it offers the beginner and advanced artist a rich diet of techniques, troubleshooting tips and talent. If you buy no other watercolour 'encyclopedia' this year buy this one. And as someone who was turned on to painting by Channel Four's "Watercolour Challenge" in 1998, it's a refreshing companion to the other two books in the series which celebrate experts and contestants. I won't be buying any for a while to come - to busy soaking up this one!
