Around the country hundreds of thousands of toanga are stored in vaults and warehouses. Our museums, art galleries and libraries simply don't have enough room to have every treasure on display at all times. Nelson artist Josephine Cachemaille has been fossicking through the storage area of the city's Suter Art Gallery, to create an exhibition featuring some of her favourite finds and work she's created to complement them. To Josephine, inanimate objects have a secret life. Lynn Freeman talks hidden treasures with her.
