I am making bags to give as gifts using those curtain grommets that are so popular. The bag is done except for the handles which thread through the grommets. I cut the holes per the instructions and even ran a hand sewn thread around the hole to keep the layers together. When I place the 'threaded' portion on the bottom side the outside edges of the hole fit perfectly around the groove. And when I put in the first grommet it fit fine but now I'm on the 3rd one and it keeps popping open. When I re-do that one and go on to the next it pops off too. Everything seems to line up well and looks like it will hold, no gaps or overly thick sections. I can't seem to make them stay together. Has anyone had this happen to them? How did you solve it? Should I use some glue? After all the hard work to get the back to this point I'm stumped. I would hate for the grommets to come apart after I've given it away. Can anyone out there help me?
