Žabjak

The activity of the Centre for Handicraft and Art Craft, Rokodelska zadruga (Handicraft co-operative), is based on the preservation of cultural heritage, the transfer of traditional handicraft skills and traditions to the younger generations as well as the development and promotion of modern products. We see our mission in developing artistic creativity and education, and ensuring active spending of free time and enriching the quality of life of all generations, so we organize various exhibitions and events as well as workshops and courses on clay creation for children and adults.
