As a teacher of coloured pencil workshops, Gary Greene sees his students buying water-soluble pencils "by the truckload." Problem is, they don"t know how to use the medium or even what it"s capable of...and until now, there"s never been a book to teach them. In this much-requested book, Greene shows artists how to achieve a variety of different effects with this fascinating medium - from loose, watercolour-like washes to precise airbrush looks. The author, along with 6 guest artists, show how they use the medium in 18 complete painting demonstrations.
