Neptune's body is made with plastic disks that were cut off one of those door curtains. The kinds with beads, etc. that are strung and hung up in door ways.
His face is composed of seed beads. His triton is gold beads. Blue mix seed beads and aqua rocks suround him.
I also used several different colored glasses, included back painted and tumbled glass. Rhinestones on his tail. Glass gems and some beads.
