Congratulations John. It's great that you're planning to include some celtic customs. My only suggestion would be to point out that "customs" should be "transparent", that is to say that any of the things you choose to add should support the ceremony and not stand out as contrived or overly showey and thus appear phony. The guests should be able to understand what's happening without a playbook. The important thing is the comitment the two of you are making to each other and your community. This is not to say you can't be creative. I hope you don't think I'm being critical, it's just that my Father is a minister and I've help him design some weddings. I've also seen some "theme" weddings that didn't follow suggestions and didn't come off too well.

Oh, and I know you won't believe this now, but neither of you will remember very much about the ceremony anyway.

Congratulations again, and may you have many happy successful years together.

Jamie
