A brief history and introduction to the actual techniques used by early Christian monks in Ireland, the British Isles, and the continent, to make what we call Celtic knotwork. Prof. Van Stone discovered this and other art techniques in 1972, and has taught them to thousands of calligraphers and enthusiasts for almost four decades. There are several instruction books purporting to teach you How To Make Celtic Art, but none as simple and direct as this. What worked 1300 years ago works today.
