R and I talked with the caterer today. At least, we thought we were there to just talk about the food. It turns out that the university catering basically does all the wedding planning as well. Very helpful, but a little overwhelming.
Our contact is a woman who has organized many a wedding, leaving her much wiser in the ways of "setup" and "flow" than R and myself are. We've decided to take her recommendation and make a seating chart, even though that was one thing I really didn't want to do. I suppose it makes sense, but it seems like torture. I make enough seating charts!
I'm thinking we might go for this invitation in ore. I had been thinking green, but the green offered is a little too yellow. The ceremony is probably going to be in earthy blues and greens, so I suppose I could go with either without a problem (as an interesting aside, I really recommend this article on tetrachromats).
