Creating your own gem clusters?

This is one of my home made gem clusters... a very large one for the center and two smaller ones for the sides. These were done with rubber cement, let dry, then I just peel them off the plastic and use body glue to attach them to the skin. Hope this is clear enough for you to see:

I did 4 test clusters they are almost dry but I was able to already peel them away from the backing. I'll try the application tomorrow, but here they are.

@Changing, what glue base did you end up going with?
