The black doodle is "Candlelight" metallic yarn. Its size is comparable to a size 20 in crochet cotton. What I like is the sparkle; what I don't really care for is how the strands separate in the picots, but that's just my personal reaction.
Then for the earring, I tried a pink quilting thread used together with a fine sparkly metallic blending filament. I like the stiffness of the quilting thread, and I like the sparkle of the metallic
filament used with it. I found the rings a bit difficult to close, however, and of course working with 2 threads used as one is tricky!
I started with a mock ring, leaving a big loop at the start. Then halfway around, I slipped a glass pearl over the loop, put the shuttle through, and tightened around the bead.
Then I finished the mock ring and joined to the beginning.
The other beads were added over picots, with the exception of the drop bead -- that one was
strung on the ball thread.
The resulting earring has a good stiffness.
I just hope there is enough of those threads left for the other earring!
