I am in the process of planning my wedding for the spring and love the idea of having a picnic after the ceremony. In order to stay within the budget, I was playing with the idea of having a potluck dinner. I know that generally if you have an evening wedding with dancing and such that you should serve your guest dinner. However, my fiance and I would provide the main course and ask the guest to bring a side dish. Is this rude? We do live in a very small town and most of the people attending are family and close friends and I don't think they would mind at all, but I don't want to be rude.
