I second using a really good, really HOT glue gun. Sometimes I'll put a clip on backwards or slightly crooked and when I try to pull it off the bow to reposition it, the clip doesn't budge. It takes some serious effort to get it to come off.
When I saw "bow security" I imagined a high profile bow with lots of bling being surrounded by security. Security: "Hey, don't get too close to the bow. Step away, please." Hehehe!
