Yary Livan is seen working his magic on a potter’s wheel. The Cambodian ceramicist had examples of his ware on display at this summer’s Lowell Folk Festival. Many festival goers asked about purchasing his ware, but the crafts area was not set up for sales. Turns out, Yary has not found a place to sell his work locally. But that is about to change. He will soon have some of his work for sale at the Heritage Shop at the National Heritage Museum. Yary is one of over 70 artists represented in the museum’s exhibition, Keepers of Tradition: Art and Folk Heritage in Massachusetts.
