Well those hair clips in my last post ended in epic fail. It seems that the bond of the E-6000 pulls the glaze off the charm, thus leading to the charm popping off. All the charms on the hair clips have popped off except one creamsicle! I have already fixed and glued the panda ones again. I will do the creamsicles later.
So! If you want to glue polymer clay to hair clips remember to sand a spot for the glue that has no paint or glaze on it; just clay! That way it will stick fine and no worries of it popping off :)! I guess trial and error is the only way to learn sometimes.
