Karma cards

Feel-good idea alert: Leave Sarah's karma cards in random places (bike racks, the produce aisle, in a stack of library books...) and brighten a stranger's day. "Tuck these sweet little cards someplace they'll be found," she says.

How sweet is that? Where would you live your card, friends? What would you write on it? Any special sentiment? xoxo

P.S. Look out for a MEMO TO MEN coming your way soon! :)
