There are grommets of all sizes - they are a pain to put in. Good luck. I've got one in a purse I made several years ago; it came off. I have yet to put it back on; it will ride around in the pocket until I'm ready to put it back - if ever. Check out SeattleFabrics.com & see if they have what you need. You can even call them if you like. I've always got good customer service from them. And you might find them locally in your town as well.
