Painting on Stones by Genevieve Ploquin

On the plus side this book is great for inspiration and good for the templates and techniques sections, giving advice on transferring designs, varnishing and materials.  However, many of the designs use more than one stone, which may be fine for you but when I paint a stone I just want to be able to carry it around alone, not stick it together with another one.

Painting Animals on Stones by Lin Wellford

A brilliant book with full colour illustrations and black and white diagrams showing you how to use acrylics to paint ladybirds, penguins, field mice, rabbits, fawns, owls, foals, squirrels, kittens and animal families onto rock.  The author introduces the book with a section on  where to find and how to select the best stones and about supplies and equipment.  Each animal project has clear pictures of equipment needed, the best kind of rock to use and simple step by step illustrations and photographs, my 7 year old is able to follow them.

Learning to Paint and Draw by Hazel Harrison

As a newbie kind of lost in the world of materials and techniques but desperate to express myself this is a brilliant book, covering briefly many aspects of drawing and painting, using watercolours, pastels, graphite and coloured pencils, oils and acrylics, and pastels.  A really good starting point.
