When someone becomes a member of the club, they can get a club badge. They have to pay for it themselves.
We order them from Majestic Badge.
Majestic charges extra for the magnet backed badges. Today (2010) it's $3 extra. We think most of the cost is for the magnet piece, and not the metal plate on the badge itself, so we might try talking to them about what the price would be if we skipped the piece with the magnet, since we could get the magnet piece for 65 cents from Pinless when we order class badge holders.
While people are in the class, they have Class Badges which the class coordinator makes.
