These would be quite breathtaking in your garden, vastly better than the polyresin animals on sale in garden centres!
The author gives step by step instructions (all illustrated) from the shape of rock required for each creature, how to sketch in the shape and gradually paint in the design. There's chimps, gorillas, bears, zebras, even giraffes (you have to tweak your rock a bit to get the shape for them!) and much more.
As well as wild animals, there's a section on a children's zoo as well- make a hedgehog, lamb, pig...and for Easter a GORGEOUS hen and chicks (one just hatching out of its shell!)
