I’ve been on a spiral kick lately. I was going for cinnamon rolls with this design, but was informed that it looked more like sushi. Later I might try a vertical, ‘stacked’ version so the sushi pattern is more obvious when the book is displayed correctly. But here you go! Advanced beginner, just because of the number of holes. Very easy to sew.
58 holes, 6″(15.24cm) wide, .25″(.64cm) thick. I wrapped the spine about 9 times to get thread length.
