What are the best words to write on a wedding cake?

I wouldn't have any.

google.com might be a good start though

Thanks all the same!?

I guess it all depends on why you need to write something and what you want it to be. You could just do something like "Love" or "Forever" repeated on the tiers. You could use a line from a poem. You could do something that ties into your theme if you have one... like if you had a fairytale theme you could use: "Once upon a time..."

Not sure if any of that helps but not entirely sure what you're looking for!

What about a part of your vows? Whether you're planning on saying the traditional or making your own, I think it would be a nice touch
