I finally got around to turning my Metropolitan Museum of Art admission buttons into useful souvenir refrigerator magnets. I simply glued a small, round magnet onto the back of each button. Yes, they’re metal and the magnets would have stayed attached without glue, but they would have also popped right off the magnets when anyone picked them up off the fridge.
Points for using junk-drawer souvenirs that would have eventually been thrown away.
And more points for using the glue gun without incident.
Entirely Adequate
