various images and ideas I like...

<--- in this pic, they enlarged a picture of themselves to be the sign pointing to the wedding.  They put some real balloons too in her "hand."

A school-themed idea

This save-the-date and the drawings below are from two different weddings, but I thought they go together well.  If you are a teacher, if you guys met in grade school/middle school/high school, if you are currently in academia, thought this would be such a fun idea.  I love the big drawings, that say Jane and John, sitting in a tree, k-i-s-s-i-n-g.  I would have it myself, because our reception area has a tree, but I don't think it would make sense without a theme.  The wedding below even had shiny red apples at each place setting.
