I found some wonderful soft blue glass rounds and incorporated them into a choker style necklace measuring 18". Chokers are normally up to 16" but because of the heft of this necklace it could be a choker. Combined with the soft blue beads are metalic grey triangle and hex beads and picasso blue seed beads, with a clasp of the same materials.
