What is a one-sentence summary of the following article?
There are a variety of ways you can customize beads or create your own dangling belly-button jewelry. Cover the bead with nail polish or a thin layer of white craft glue, then roll the bead in glitter. Let it dry completely before you attach it to your body. Instead of sliding beads onto a straight pin, stick the pin through all sorts of materials. You can decorate a tiny Styrofoam craft ball with paint, nail polish or glitter or roll a small ball of aluminum foil and decorate it in the same way. You can even stick the pin through a small fuzzy ball. Just be sure and stop before adding a post or hook and instead attach the jewelry to your belly button using the instructions above.

Summary:
Create custom fake belly-button jewelry just like you would create custom earrings. Customize your bead by painting it with nail polish or covering it in glitter. Create dangling earrings with a variety of materials. Follow the instructions to make any earring design.
