If you send a wedding invitation to the President, you will receive a congratulatory letter from him and the First Lady. I don't care who the president will be when I get married, I have to remember to do this! ps, it works for mickey mouse too.
Great as invitations, but gives me an idea for thank you cards... Use pics from your wedding photo booth - one or two of the bride and groom and one of the guests you're writing to. Attach to labels which match your wedding stationery and write a lovely note. Perfect! #noblehound
