Bonnie Bishoff coiled loops of tigertail (nylon coated wire) and embedded part of each coil in striped half-circles of polymer to make this light, bouncy necklace. It can be doubled into a short curly version.
Assembling it must have been tricky since the necklace would have to be constructed first and then baked. The wire adds to the graphic quality of the design. There’s another example on Bonnie’s Pinterest site.
