Once upon a time the stars in the heavens crossed
and so we met…
Share our day of romantic celebration as we
Together with our parents,
Sasha Last Name
and
FH Last Name
will exchange solemn vows of love
on Friday, the twenty-seventh of May
two thousand and five
at half past two in the afternoon
Name of Church
Street Address

Come celebrate the union
of our lives and our families.
