For each earring you will need an earring hook, a small jump ring and a glow in the dark star. Open the jump ring slightly using needle nose pliers.
Make a hole rin the top corner of star with a nail or a sharp needle. (Be careful I managed to make my finger bleed with this step but I wasn't paying attention.)
Slip the jump ring through the hole.
Slip the earring hook on to the jump ring also.
Close the jump ring and prepare to glow.
