Here's a simple tut if you have extra wires. Don't throw them on the trash yet because you can make something out of small pieces of wire.
To start, gather at least 6 wires in different sizes. As much as possible, pair 2 wires of the same length to have at least 3 sets.
Pick up the longest wire and with your round nose pliers make a loop at the center of the wire. This loop will serve as your bail. Shape the wire using your fingers or any round object to make a heart shape like so.
Then make a loop at both tails. Do the same for the other 2 shorter wires/ You will then have 3 hearts in small, medium and large size.
When you're done making 3 hearts, open up a jump ring, hook it up onto the hearts loop you first made at the start and link the large and medium heart. Open up another jump ring and link the medium and small heart. Attach your ear wire and you're done! As simple as 123!
