There's nothing worse than having one of your spiral bound teacher editions start to fall apart become the spiral pops through the top hole. And once it has slipped out, it's tough to get it back in.
But don't worry! Just hot glue/super glue a pony bead to the end of the spiral, and your spiral binding will stay bound!
Color code your beads and you'll be able to pull out the right book on the first try every time, too!
