Finished drawing from yesterday. My math skills are not the best but I calculate this drawing to have over 1,591 feet of ink lines. It consists of 36 line plots. Each has 48 points at the circumference. The widest pattern is about 15-1/4 inches in diameter making the outer-most line plot longer than 61 feet, not accounting for the curves. Each successive pattern is 1/4″ less in diameter. That’s a lot of ink, two Copic 0.07 black ink refills expended. And a lot of down time waiting for ink to dry so I could draw more lines on top.
