So, with that said, I have been considering using screw-in bails. The nice things with this is that you can see the letter on the back of the pendant and there is less chance of the screw coming out than the bail coming unglued. Another nice thing is that you can use different size chains. To this point, the bails only allow for small size chains. The bad things are I'm not sure the screw-in bails look as nice as the glue-on bails and I would have to include a split ring with each pendant. Also, it may be a bit more work to get the screw-in bails attached.
So, I need your advice as to what you like best! To the right of my blog is a poll. Please vote! I need feedback! The picture below shows the 2 types of bails. The first 2 pendants are the glue-on bails, the next 2 pendants are the screw-in bails.
