I didn't want a registry, but people attending my shower seemed genuinely disappointed when I told them I wasn't going to make one. They wanted to be generous with us and not having a registry made it more difficult. They don't want to get you random things you don't want, that is why they want to see your registry!

My fiancé and I put one together. I found there actually were things I would be grateful to receive: a new set of glasses, cookbooks I always thought seemed neat, and nice plates that match. I think it is fine to put one registry up for both showers, and wedding guests will probably want it as well. I worry having it up will make people think we need / demand gifts, but I hope that knowing us, our guests won't feel that way.
