Thanks for those references. I missed those videos. I would have never thought a simple larks-head knot would work in this application, but it appears to be perfectly-suited to these tiny wires. Brilliant--I will definitely try this in the future...
i agree. the larks head knot is brilliant. i tried it yesterday just for kicks and it works. its a little tough to cinch the knot completely closed, but some hemostats or pliers oughta help.
