To bead this choker, I did netted weave using twisted, light aqua, twisted, bugle beads;  teal and black, size 10, seed beads;  and teal green, Czech glass, drop beads.  

Because I added and extender, the length is adjustable; starting at 30.5 cm. (12"), up to 47.5 cm. (18 3/4").  

It closes with a black, lobster claw clasp.

If you would prefer the tail loop up rather than dangle, just let me know at time of purchase, and I can easily add a hook. at at the end.

The last photo shows more of my work.  

If you don't see the listing in my shop, contact me and, chances are, if I don't have it in stock I can probably make a custom necklace for you.

This is a simple version of the amazing collars made by Native-Americans, for centuries, up to the present.  

To see some examples, go to the National Museum of the American Indian (NMAI), and search under beadwork/netted weave.
