I am looking for an item that I am not sure exists. I would like to
secure the ends of a 3mm rubber necklace cord so that the cord length
can be adjusted by the wearer of the necklace. I imagine a simple
holder that looks like a figure eight so that both ends of the cord
can pass through. Two of these would be used with each crimped onto
opposite sides of the cord. You could then slide the ends around to
adjust the cord length. Probably not a good description, but it is
the best I can do without a picture. Does anybody know if this
exists, or should I just make my own?
Are there any other adjustable length mechanisms that will work on
3mm rubber cord. I would prefer if it never comes apart and just
expands to fit over the head.
