Love Delivered with Lunch

I write on my daughter's banana every day before I put it in her lunch. It's a good exercise in creative writing, coming up with subject matter to fill a banana a day. But I am fond of sending love notes of all sorts, especially notes in lunches. And I've seen a few other varieties you might consider sending off with someone before Valentines.

I love the idea of
skewering a sandwich with a love flag or maybe a love umbrella
or including a typographic napkin
or a loving egg (isn't bento the coolest?)
or repurposing a bread clip
or including the love message in a secret envelope
or an edible envelope (via here)
or sending the whole shebang in something with character.

And finally, I'm not sure if you've ever seen this one, but here is a printable survey to tuck inside, which I completely love.
