Here are all the materials needed for this craft. I gathered some dangly earrings I don't usually wear, and some nice charms. The paper clip is only for those who don't have dangly earrings.
First, you need to take the earring off of the dangly part.
Take out the dangly part of the earring and the charms from earlier.
Now, attach your charm to your dangle.
Here is a picture of the finished product.
Here is what the finished product looks like when you wear it!
