I also like to incorporate "hinges" in my necklaces. This gives a pivot point that does not stress the thread. Here I have connected separate modules (the starfish) with loop in loop hinges. For more information on this method, look up the back issue of Beadwork magazine: Beadwork. "Stress Redux: Send in the Reinforcements!" by Joanne Strehle Bast, Summer 1998 issue.
I am also using as a closure the boro glass toggles, also provided by Artbeads. I really like the use of a catch that does not add a distracting metal element into the beadwork. Joanne
