This is my first attempt at flat spiral:
It is a "graduated necklace" - not exactly graduated, but the portion in front is larger than the side pieces, because it has a large rondelle as the center bead, and the side pieces downsize to a 4 mm firepolish bead in the center of the spiral.
Flat spiral works up incredibly quickly; I have seen a lot of bracelets in this stitch, and have always wanted to try it.
The center portion of my necklace, with the rondelle, would make a terrific bracelet. I am withholding opinion on the necklace until it is finished; I'm not sure whether I like the effect. And I'm worried that the center portion won't lie flat against the neck. We'll see!
I have to stitch about 1.5 inches more on each side, and then I am going to create a hand-woven clasp, because nothing in my stash is quite right for this piece.
I'll show you the results when it's done!
