Trim the leads

Use your flush cutters to trim all the leads until they're no longer poking up past the solder joint from the back of the board.
Ensure that none of the wires are long enough to bridge a connection to other leads or poke your hands during use.
This is a great time to clean up any residue left from the solder. Apply some isopropyl alcohol to the solder joints and wipe with a lint-free cloth to soak up the flux and alcohol residue.
