Bethy, to work out chinese Knot, you have two options - traditionally, people use satin cord, there is reason for it, because chinese knot requires a lot of adjustment after the tying process, if you use wires, your wires will get stiffer and wont allow you do twist after a few adjustments. So in order to make Wired Chinese Knot, not only need alot of experiments (there are a whole lot of my creations that failed miserably that never would see the light again), you need a lot of patience.
May I please suggest you this book: Chinese knot with beaded Jewelry
This book was recommended by some of the friend I met in another forum, and they ranked this book to be very helpful. :) Alternatively, you may search on the internet for some free instructions - but it would be in Chinese Characters..
Hope these help. :)
