I have been pinning up a storm on Pinterest, and when I was looking through my DIY inspiration board, I came across this lovely heartbeat necklace (sold on etsy here). With some wire and chain I was able to create my own!
Leaving an inch of straight wire at the beginning,
use the tip of your pliers to bend the wire to create a heartbeat pattern.
More steps after the break...
Bend the wire until you create your heartbeat.
Make a loop on each side of the straight ends, attaching the chain to the wire.
On the other end of the chain, attach the lobster clasp with a jumpring. Add a jumpring to the other side of the chain and clasp.
