Gluing down mancala beads

[mezzanine27.livejournal.com]

i was recently expiramenting with making bobby pins. i glued little pictures to mancala beads (i'm sure there's another name for them, but i can't think of what it is.) then i glued the beads onto the end of bobby pins. they turned out really really cute, but the beads kept popping off of the bobby pins. the pictures came off the beads a few times too. i tried hot glue and super glue, but neither worked. do any of you have ideas of a type of adhesive that will keep the beads (and the pictures) secure?
