If you have a pair of earrings that need some color, you can liven it up using nail polish and it will have an enamel effect. All you will need are a pair of earrings, bright colored nail polish, clear nail polish and tape.
First, you need to cover with tape the parts of the earring that you do not want to paint. Since the earrings have glitters, I added 2 coats of clear nail polish to create a smooth texture.
You may want to put a piece of paper towel on the surface where you're working. Add two coats of colored nail polish. Let it dry for a couple of minutes and add two coats of clear nail polish.
When the nail polish has dried, you can then remove the tape.
While they're still wet make sure that the earrings do not touch each other so that the nail polish won't get messed up. Wait for the earrings to completely dry before you can wear them. :)
