Lovely necklace! I was totally blown away by Beader's Secret, too. I'm a complete convert.
I had a ton of beading silk. I gave it all away. No point in junking up my stash of supplies if I'm truly never going to use real silk again. I couldn't even repurpose it for weaving, sigh. I thought about using the silk up, and then thought, NAH, life's too short to suffer.
