The picture below shows two (2) braids using the spiral ridge design. They both use 12 cords but different movements. I wish you could really see the difference more clearly.
You can find the pink-purple-white one on Youtube. Search Kumihimo spiral rigde.
The teal and brown on is from a design in the book, "Kumihimo Wire Jewelry", by
Giovanna Imperia. You can find it on page 29.
