It is really simple like Vermin Jerkins sugar drop earrings :P I haven't tried this though :P it will work it is just really, REALLY simple!! :)
First, clean the earring posts with nail polish remover or soap and water.
Okay, now if you're going to use beads add a layer of glue and stick the beads and again coat them with another tiny amount of glue and you're done with the beady ones .
For the magazine ones better use better use comics :D or beauty magazine. cut out the magazine or comic in the size of the posts and stick with paper glue.. add the hot glue and DONE!!
Now the last one for the glitter ones add a layer of paper glue, add glitter and add the hot glue!! FINISH!! :D
