The Watercolour Sourcebook is a compilation of four selected titles from the What to Paint series, chosen specially to illustrate the wide range of scenes and subjects that can be captured in watercolour.

The works of four master watercolourists – Geoff Kersey, Terry Harrison, Peter Woolley and Wendy Tait – are brought together in a collection of 60 beautiful, detailed projects on the subjects of trees, woodlands and forests; landscapes; hills and mountains and flowers respectively. Each project results in a full painting that is accompanied at the end of the book by a full-size outline that can be copied and applied to the artist's own watercolour paper using tracedown paper and pencil.

The Watercolour Sourcebook aims to provide a wealth of inspiration to the painter who struggles to decide upon their subject matter, and arms the artist with everything they need to know about what they're about to paint, from colour palette to useful techniques.
