My mom is a quilter and brought me a bag of goodies. In the bag was this thread. Had to try it, and updated daughter's frozen rod. Picture doesn't do the "sparkle" justice
Looks very similar to a thread I've used for jig bodies. Below is an example.
Gütermann Metallic Sparkle Thread (Multi/Rainbow Black - #071) has been available at fabric and craft stores in the recent past. It has a nice appearance too imo.
Yeah I've used that stuff before but this is cool the way it braided I'll take a picture of the 1-3 in sections I cut off would make good lateral lines
