Use heavy-duty flush cutters to cut approximately 1 loop from the spool of 12-gauge antiqued copper wire. Make sure both ends are cut flat (flush) so they fit together well inside the crimp.
Slide nuts, washers, large-hole beads, holey found objects, etc onto the wire.
Place one end of wire half-way into crimp connector. Place other side of wire in the opposite end so wires meet in the middle.
Use the back notch of the Mighty Crimping Pliers, to gently - but firmly! - squeeze one side of the crimp, then the other for a secure connection. This is the notch closer to the handles, not the tips. For a professional look, place the divot on the underside of the crimp (the inside of the bracelet).
