So, I made this Necklace last week. It was really fun. I wish I had taken pictures when I was making it. Atlas, I did not, and I have no more of these fine chains to remake. lol!!
I think the picture is pretty self-explanatory to your eyes.
The bib is made with 1mm chains dangling off a 20GG SS half hard wire. It is 1 1/2" wide (end to end) and chains are 2" long. I put 2mm SS seamless beads in between the chains to space them out. And amidst the chains, I dangled some Cubic Zirconia briolettes and 4mm round beads.
Note: Before you start the bib, you should attach the Neck chain on one end loop first! I forgot and had to remake the bib. ;( I wasted the heavy gauge wire. lol!
Enjoy and let me know if you have any questions.
