You will need a larger calotte so that it can easily cover over knots or cimps that are joining the multistrand together.
|1) When you have multistrands of wire/threads, it is a good idea to use 2 French crimps to securely the threads together.
Clip the ends of the wire threads after flattening the crimp beads.
Put a calotte around them.
|2) Using a pair of flat-nosed pliers, squeeze the calotte closed tightly but without damaging the thread.
3) Repeat on the other end of the multistrand piece.
|3) After that, apply the fastener of your choice to finish off your piece.|
