I like the idea of something simple. How about a 4-5 inch square of yellow (easy to spot)fabric with QMB stitched (painted-written in permanent marker--however) Name, state and screen name. Pin to jacket or blouse or whatever. I thought of the bright color because years ago we sponsored a bus tour to a show and wondered how we would keep track of everyone, so made bright orange squares with their names on. It did make the patrons easy to spot in a crowd. Was a conversation starter too. We used those orange tags for quite a lot of years--it was kind of a joke after a while. "OH, your on the bus".grin
