STEP ONE: paint your hairclips with your nailpolish, paint only the top, let it dry.
STEP TWO: When your nailpolish is dry and your glue gun is heated up, glue your beads on to a part of the top of your hair clip. Do this buy, flipping the bead over and putting a dot of glue on the top and bottom of it's back. Then flip it over and stick it on the clip.
STEP THREE: make sure everything is dry, then stick it in your hair and gaze at how unique you look in the mirror!
