Summarize this article:

They can be pretty beads, buttons, or even rhinestones. Choose something that is about the size of your earlobe and not too heavy. If you are using coat buttons or stud earrings, snip the prong or loop off using a pair of wire cutters. If you are a child, ask an adult to help you with this step. There are two main types of clip-on earring backs: the skinny type with a bar in front, and the larger type that are shaped like a disk. The skinny type may be more discrete, but they will be more painful to wear. The larger ones will be less painful to wear; they will also be easier to decorate. Consider getting some clip-on earring pads. You can slip them over the back of your clip-on earrings to make them less painful to wear. Be sure to cover the entire front evenly. Don't apply any glue to your item. Make sure that they are right-side-up. This should not take more than a few minutes depending on the brand of glue. For more specific drying times, refer to the label on the bottle. Pull open the earring and position it over your earlobe. Close the earring. When taking the earring off, do not yank or pull it off. This can damage the earring. Instead, open the earring back first, then take the earring off.

Summary:
Choose two matching items with a flat back to use for your earrings. Choose a pair of clip-on earring backs. Spread some super glue over the front of the clip-on earring backs. Press your two items into the glue, flat side down. Wait for the glue to dry. Wear the earrings.
