Neck rings were a ritual that Thailand women usedThe rings were put around the necks producing an effect that although more of an optical illusion than real elongating it has the unfortunate characteristic of seriously oppressing the collarbones and ribs into an unnatural shape.
I am assuming you are not trying to actually create the hard metal neck ringsTo duplicate the appearance of them you can use aluminum foil rolled and curved into a circular shapeThe other way to go is to use thin plastic tubing that you paintHope that helps.
