Yikes...those came out huge! The two strands are strung separately, using a double thickness of #20 Beader's Secret thread (wonderful product, from Etsy:
https://www.etsy.com/shop/PatriciaSaabDesigns?ref=ss_profile And some sterling silver and cz clasps I had in my stash. And wow, my knots look pretty large too...but that's because of the 1.8mm drill holes. I needed to tie larger knots to keep them from slipping up into the beads.
The bracelet is made up of 8 beads and 22 gauge sterling silver wire, sterling flower end caps, and sterling silver toggle clasp. I usually use two passes when I wire wrap, but did three with these beads as they are all greater than 13mm.
I purchased the beads from Ultimate Jadeite and the findings came from various sources.
