Was at a Ricky Tims' seminar yesterday where he covered this and showed a number of variations he had done. I also have the book. The most intriguing (IMHO), were made from his hand dyed fabrics with spirals. I'm a bit of a traditionalist, but after this seminar (also featuring Alex Anderson) I will be trying a few if their ideas. Ricky explained that his instructions were to get you started, then let your creative brain take over.
