Trim chain to desire length (necklace shown is 16").  I think this necklace looks better shorter because the centerpiece hangs almost 4" down.

Use your pliers to open the eye of an eyepin.  Hang your butterfly from it's top left corner.  Close the eye.  Place a czech glass bead on the pin. On the other end of the eyepin, use your wire looping pliers to make a loop facing the same direction as the bottom loop.  Use this loop to hang your beaded butterfly from the square filigree pendant (turned to a diamond shape).

Open another eyepin and attach it to the top corner of your filigree diamond pendant.  Place a czech glass bead on the pin and use your wire looping pliers to make another loop at the top as you did in step 2. Use this loop to connect the whole thing to the center link of your chain.

Four links from the center on each side, use the same looping technique described above to attach a czech glass bead with an antique copper bead cap on either side on an eyepin.

Use tweezers to place an antique copper split ring on each end of your chain.  On one side, also attach the antique copper lobster clasp.

Use some extra chain (the necklace shown used 2") to dangle one more czech glass bead using the same wire looping technique and either an antique copper eyepin or a headpin if you have one.
