It's a good idea to add a short note about what you will be using the money for so guests feel more connected to you and your plans. Possible ideas include a home renovation, a honeymoon, or even a savings fund for the family you hope to start one day, Swann said.
Again, be careful in how you phrase this. In a column for HuffPost, etiquette expert Anna Post suggested you could say, "We'd like anything you think of, though we could really use help with our honeymoon/first down payment on a house."
Another suggestion read, "Sara and Carlos have pretty much everything they need, but there is a fund set up in their name — that might be the most helpful."
