Use your nipper tool to cut 6 links of chain.  Use your chain nose pliers to open the loop of an earwire. Hang your 6 links of chain from it.  Use your chain nose pliers to carefully close the earwire.

On a headpin, place: (1) 4mm round bead, (1) beaded bead, (1) 4mm round bead. 

Above your three beads, use your wire looping pliers to make a loop in your headpin.  Hang it from the end of your 6 chain links.  Then wrap the wire around itself a couple of times and trim the excess with your nipper tool.  Repeat for a matching earring.
