There has been a wonderful discussion at the Faber’s Piano Teacher’s Forum about helping parents remember to pay at the beginning of the month. One of the teachers made up some Oops! cards. If a student doesn’t give her a tuition check, she will send them out to their parent after the lesson with a card in hand. She uses a “friendly” font, and prints the cards on bright green paper. I loved this idea, and made up some Oops! cards of my own. They will open in an MS Word document, so you can change them to fit your needs.
