Gather materials and plug in your glue gun.
With your jewelry plyer (or your fingers, these chains are pretty easy to twist off), cut one 20" piece of biker chain, and one 20" piece of mini black chain.
With the plyer, carefully open the end links of both chains. Leave only enough space to slip the hair elastic through.
Attach the chain link to the hair elastic.
Close the link with the plyer.
Repeat with the other chain.
You are going to repeat the last two steps with the other ends of the 20" chains.
Here is the chain necklace.
Bring out your first butterfly applique.
Flip the applique so it is upside down.
Place a line of hot glue along the back of the applique. See the next step photo for a better idea of where the line should go.
Secure the chain on the applique with the hot glue. Be careful not to burn your fingers! We pushed down the chain with a pen cap.
Bring out the second butterfly applique.
Cover the first butterfly/chain applique with a generous amount of hot glue.
Now place the second butterfly on top of the glue. This is going to make the necklace reversible! You can always use a different color butterfly so that the necklace has two wearable options!
Press down firmly. You want to make sure that it is secure.
And now you have it! Let the glue dry (only takes a few minutes) and put on your necklace! The hair elastic makes the necklace stretchy so you can just pull it over your head :)
