Did I mention I also couldn't find my beading wire? So I used some thin cord instead, which limited me to beads with wide holes. But then, since I didn't have enough spacers, some of the wide beads I wanted to use slipped right over the double row of silver seed beads I used instead. And then my beaded loop was crazy long, so I twisted and secured it with the round ring part of a necklace fastener by squooshing it with needle-nose pliers. (I couldn't fit a crimp bead in in the small space.)
So it's all quite improvised, but once I make it out to a store where I can pick up some more supplies, I think I'll go ahead and try another!
Thanks again to Tammy and Angela!
