Great idea! I moaned in my latest post about how my daughter's new bike got stolen only three months after we bought it. A commenter left a link to something which runs along the same lines:http://www.dominicwilcox.com/stickers.html
Unfortunately just the suggestion of green stuff growing on it would probably put me off my own sandwich, thwarting the purpose. Thamks for the comment.
I think a Brief Safe would be even better as a deterrent... but I suppose that would open up a whole new set of problems at the office lunchroom.
mouldy sandwich bags and pooey pants? we see those every day at the gimcrack :-)
