I am, as you can see, still fussing with the spiral chain and how to stop it from un-spiraling. So I tried this. I made it fuller so those gaps could not open up. By doing the stitch where one adds a big bead and 5 or 6 smaller one, and then repeating it without adding the big bead one has two step-ups for each stitch. This doubles the number of outside beads and fills it out.
Part of this exploration is in trying to get done an entry in the Fire Mountain contest. For two days I have worked on it, trying this and that, abandoning whatever and trying to listen to the necklace.
