Okay, gather all the things that you'll need.
1. Pony tail or hair clip, anything you want that has a cute accessory in it. Then remove the 'pendant' thingy. Hehe.
2. Mighty Bond. I don't know if it's available outside the country but, you can use Hot Glue Gun instead.
3. and, your old Ring! :)
Glue your piece into the ring.
Let it dry for 20 to 30 minutes. The longer you wait, the better it gets. :)
TADA! You're done and ready to make some more. :)
