The HiyaHiya people were able to help me out, and I felt a bit stupid for not having thought of them in the first place. My friend was able to bring me this 0.5mm steel crochet hook, and it works with my beads. I am now making wonderful progress on the second Emily2 while my other lace cries for attention.
Speaking of HiyaHiya, when I got my new hook, I was also able to see a set of the new bamboo interchangeable needles. I think I know what I want for my birthday this year!
