John Shaw-Rimmington has, in the past, specialized in restoring historic stone buildings. After working for the Uxbridge museum he extended his focus to using stone in landscaping and building dry stone walls. His knowledge of designing with stone has developed after years of masonry practice in Canada and comprehensive research into traditional dry stonework in Britain where he worked with a number of professional wallers . He teaches walling in southern Ontario and has designed and built many dry stone art installations across Canada as well as built a number of dry stone bridges in Ontario and Quebec. As well as doing many demonstrations and lectures, John is the president of the Dry Stone Walling Across of Canada (www.dswac.ca), and also writes of a daily blog called Thinking With My Hands.
