slip the prongs of a pendant bail through the hole on each heart. close the prongs by gently squeezing the bail between the jaws of the pair of flat-nosed pliers. For the pendant: slip a jump ring through the loop of the large heart’s bail and then through the middle link of a silver chain necklace. close the ring with pliers. For the earrings: open the loop of an ear wire and slip it on to the loop of a small heart’s bail. use the pliers as before to close the ring.
