Reply to Anyone any good at soldering? Quick earth/ground question...

I want to solder 4-16 arcade buttons together. As they can all share a common ground/earth I figured I could daisy chain each button's ground connection in series (rather than give each button its own individual wire connection to ground).

What's the best way to solder the ground wires across each terminal? Is it better to cut lots of separate wires and then solder each one across to each terminal (so that each ground terminal requires two wires) or is there an easier way? (possibly using shrink wrap and one long uncut wire).

Hope that makes sense...
