It turns out that the old Christmas lights which I showed you yesterday, was not one continuous cable.... but that the cable was cut at each fitting. So I have lots of short lengths of cables.
Inside each cable is a bunch of fine copper wires. Certainly worth keeping - for a yet to be determined project! I'm not planning to strip them just yet. It may well turn out that I want to use them as they are... and they are easier to store in this state.
I've also saved these plastic rings... they'll come in handy, too... and for the moment they can live in my bead jar.
