Practice Makes Perfect (in Slovene “Vaja dela mostra”) was a two year collaboration with Mr. Urban Magušar, the Slovenian clay artist who created the concept and brought through an immense project connected to people with disabilities. The project gave me an opportunity to closely work with the participants and also with their mentors . It helped them to achieve a much better technical level of their knowledge as well as their understanding of aesthetics and art. The project was supported by the European Union. One example of our collaboration is the big mural (4m x 5 m) on the outer wall of the school building of Cirius, Kamnik that was made by heavily disabled students and their mentors as a group project in clay.
