I take the plastic piece off from the back, then I pull apart all the layers. I leave off the center piece. Then I hot glue each layer the way I like, then add a rhinestone in place of the pearl/diamond center.
When I attach these to an alligator clip, I use the flat side of the clip. I attach the flower with E6000 and use 2 alligator clips to "hold" the flower onto the clip, since sometimes the center does not want to stay down. Hope I didn't confuse you
