1. Place the sheet in front of you in portrait (vertical) orientation.
2. Fold up the bottom 3 inches with a clean score and re-open.
3. Fold the bottom left corner upward to make a triangle against the scored bit.
4. Re-fold the bottom 3 inches upward.
5. Punch on the left and insert in binder.
You now have it bound with your other organized papers, yet tidy and protected from marring, as the length of it doesn't drag beneath the boundary of the binder edge.
