I am making a pendant for a gift for someone, I have sculpted the base and baked it already and now it just needs to be painted. But I will be adding a stone arrowhead to the bottom. Would simply hot glue of a glue gun work? I have a bunch of other random cements and super glues. But if hot glue would be good and bond to two well enough where I don't have to worry about the stone slipping out at any point I will do that.
