Today I finished a second session on this lower leg wrap of Celtic knotwork. The pattern started with a knot found in a band in the 9th century Book of Kells. That was expanded out to a grid, with three of the knots running vertical and two around the ankle running horizontal. I think the artistic monks would have been happy to see their careful geometry adapted and reused in this new form.
