I bought some large curtain grommets, and they came with no instructions at all. I found one post on here that said to cut out the hole to the correct size, and just snap the grommet pieces together, or tap them with a rubber mallet if they won't snap. However, mine look like the inside of the ring needs to fold back on itself a little bit to hold the two sides together. I'm kind of at a loss on how to get these put together and can't find directions anywhere. Thanks in advance for any help you can give me!
