I have made a few wedding quilts over the years. I had started using my monogramming mode on my machine to write to appropriate info on the binding. The one that became the 'greatest hit' ended up having all the info on one edge and various newlywed appropriate sayings on the others. The saying that I still thing most appropriate was "The greatest gift one can give to another costs nothing. It is called Love".
You have been given a lot of good advice here. I do really like the idea of two semi-matching throws.
