Oh, please help me! The boutique I sell to wants snap clips covered with rhinestones. I have tried hot fix and a generic flexible glue and nothing will stick to the clips, even after I took sand paper to them to rough them up a bit. Any thoughts? My next try will be E6000, but I think they are just going to pop off like the others and I hate using that stuff around my kids (not to mention the kids that put the clips in their mouths). Both of my tries looked great and stuck well until I unsnapped and opened the clips. At the point they all came off. The rhinestones stuck together in a straight line, but fell off the clip. What glue sticks to metal? Please let me know if you have any thoughts!!!
