Dumb question, what do you use the molds for?
I'd like to fill them with melted chocolate, which I guess should work pretty well.
What else do you use them for?
Are you letting the hot glue cool completely before taking the cabochons out? That might be part of the problem, I let mine cool at least 5 minutes. And the cabochons came from Amazon
The ones that I used didn't (the flower I used in the example was plastic). But just to be safe, you might not want to let your hot glue gun get super super hot.
