Make a hackable LED ornament.

Step 7 Twisting wires.

Now the circuits are all commoned you can twist each pair of wires leading up to each socket. This could be done by rolling the socket between two fingers or if you don't like straining the contacts you can grip the wire just below the socket and twist it from there.

In the picture I have also added a common power supply wire to each common joint and sleeved them with heatshrink sleeving. You could attach the wires directly from a plug-in power supply like this and wrap them in insulating tape if you desired.
