How Do We Request No Gifts On Wedding Invitations?

On the invitation, you write  " You are cordially  invited (blah, blah, blah)  and then say something like......"No gifts, please.   Your presence at our wedding is
all we need."  (Or "all we want")  (Or "enough for us.")

Anyway, you get the idea.
I got an invite like this once, and I thought it was so sweet.
