Almonds....

We are doing 5 almonds in each box:

Five almonds signify five wishes for the bride and groom: health, wealth, happiness, fertility, and longevity.

It's 3 - I actually ripped a little blurb out of a bridal magazine about it but I forgot what they stand for.

Edit: Crap, you're right it is 5 lol My brain is scattered today

I just found this which I thought was cute. I might want to use this on the favor :)

Five sugared almonds for each guest to eat
To remind us that life is both bitter and sweet.
Five wishes for the new husband and wife --
Health, wealth, happiness, children, and a long life!
