I have a friend that has been making bags and using the large grommets also. Her bags the fabric pulling out from under the grommet and the grommets pop off easily. They snap together when she puts them on the purse but don't seem to hold tight together afterwards. I am trying to help her figure out a way to solve this problem, but not sure what to tell her. Maybe the super glue would work for her. Any suggestions, would be appreciated. Thanks
