Sorry - I just now saw your post about the wish box.
We set up a table near our gifts with a sign that said:
We have created a wish box for you to share your wishes for us. We will open the box on our first anniversary. Please write your wish for us, seal it in an envelope and drop it into the box.
It might include:
Words of Advice
Your favorite Bible verse
A romantic sentiment
A lighthearted joke
Something you wish you knew when you were first married
We look forward to reading these cards on October 10, 2010 as we celebrate our first anniversary.
When I thanked our guests for joining us for our wedding day (at the reception), I talked about the wish box briefly and asked them all to consider leaving us a note.
