When Grace's mother was a little girl, her mother (Grace's grandmother) wanted her to learn how to play the piano. The family didn't have enough money to buy a piano, but they did have enough to pay for lessons. So Grandma took a long sheet of paper and drew all the keys of the piano on it. Grace's mother practiced on that paper piano for years. Later, Grace's mother made sure that Grace, Lissy and Ki-Ki learned how to play the piano as well.
