For those who have not seen kumihimo before, it is done using this disk. You move the threads from one place to another, placing beads each time to create the beaded cord. Here is a video I found that explains the basic movements:
It is pretty fun to see how the beads all line up by each other and how the threads all overlap to hold them into place.
The bobbins are really helpful as they help keep the process tidy. I'm noticing that the cord has a natural tendency to swirl. Making this cord has helped me visualize how I might make color patterns through stringing different colored beads in different sequences.
