Thank you so much, PD, BWeaves, la_corsetiere, pattye, GemGeek, Sunseeker, and lary007! It really means a lot to me to have the feedback from seasoned makers here <3 I'm still feeling my way around some of this, but the friend I made it for absolutely adores it, and that's the most important thing!
pattye, I think I spent maybe ~8-10 hours all told on it once I had all the materials? I did it in fits and starts over 3 days so I wasn't keeping too much track, but it definitely was somewhat involved. I haven't done such tiny wire wrap before, so it had a scoch of a learning curve, but I picked it up fairly quickly and those pliers are a Godsend. I originally just had the 3 main chains with the statement pendants, but it felt like something was missing, and the labradorite did the trick - it helped visually separate all the bright whites/silvers by giving the eye a softer rest in between. I wish that I'd shot the necklace on something other than black - the pearls have such a magnificent green overtone that just glows in certain lights. It goes super well with the dress my friend has for her role, too - she sent me a pic of her first night wearing it the other day, and I'm so excited about how well it fits!
I really enjoy doing this, and I'm super happy to be able to have the wonderful forum members here as a resource. I've already learned a ton!
