How do I connect new wires?

Needing to possibly use it in schematic and pcb at a later date is why I asked.
I do make them the same colour and by appearance they look as if they are connected.
I wondered if there was a way of connecting them but Old Grey makes a good point when all I am doing is making a layout diagram of the components and you can't connect wires that way unless you strip the cable at the bend point, not really a practical thing to do.
