The original wood block was 2.5"x8"x8", and the final piece is about 7.5" in diameter and 2" thick. The trefoil knot is formed by the raised edge which goes through the three holes, so this trafoil knot is embedded in a genus 3 surface. The curve, if seen from above follows the pattern usually used to draw a trefoil knot on paper, with alternating over and under crossings. It therefore shows the 3-fold symmetry of the trefoil better than if it had been carved as a (3,2) torus knot.
