The shape is a spiral, going two rounds around the body, but all the ends connect at the same place.
AFter I had a strip that was long enough I used paper bag clips to make the round centers. This would have been so much easier if I hadn't lost my awl and had to do the holes for the clips with a seam ripper and a small pointy (but not sharp) metal stick that I found.
Then I measured out where I wanted the vertical bars to be and cut them out of worbla.

Wrong side of the belt. I haven't decided if I'm going to glue the back ends of the paper bag clips or not.
The seam where I butted the strips together is hidden under one of the strips of worbla.
