I have a long-departed friend named Wally, who was a saving kind of guy. Never threw anything away. Now, Wally wasn't the type to replace strings merely because they sounded dull...

But, once a string was actually broken (assuming, of course, that it couldn't be knotted and restrung on the guitar), he'd weave the cast-off one into a Turk's-head knot, which he'd then wear as a men's ring or use as a scarf ring on his sailor costume.

Kinda different, was Wally. But the Turk's-heads actually looked quite lovely.
