Deb :
Dagi,
It wasn't the spiral I was worried about, it was the ends. After weaving the threads on the ends and making huge knots, I glued the knots with Hypo Cement, Then, I used a wire loop as we do with our kumihimo and smushed the bead cap onto the glue/beads/knot/wire. It still doesn't sit straight, but I'm not taking it apart.
I always end my spirals with a seed bead loop, coming from the last of the center beads and going into the last of the spiral beads. No caps, no cones, just seedbeads (OK, I'm a case for the ISBU - Intensive Seed Bead Unit. 
). To that loops I add the final closure, mostly a button and loop or a bead and loop.
Deb : I just might have to start that Beady Ford Clinic for the hopelessly bead-addicted after all! With, of course, a special wing for spiral addicts!
If I can bring my beads to participate in beading therapy I'm there! *laughz*
