The club has professionally made hard plastic badges, but the class has paper badges that go into clear plastic badge holders.
Badge Holders
We've been using the pin-back badge holders for a long time, but recently we tried the slightly more expensive magnet backed ones, and people really liked those.As of 2015, we have a large number of magnet backed badge holders. Use those. We also have some pin- backed ones, avoid using those.
If the badge holders break, or get lost, or there aren't enough of them, we need to buy more. For the magnet-backed ones it's probably worth shopping online to bring the price down. Brian got them at Pinless where they're now (2010) up to 90 cents per badge for 4"x3". (There's a cheaper one at 60 cents but the magnet back on those is smaller and easier to lose. We could use them as a source of replacement fronts, though. They also sell replacement magnet backs.)
