My mom used a coffee can lid for her Yo-yos. Her quilt took 15 years to make... she would spend weeks cutting out her circles and saving them in her little tote, then take it along with her on a one week vacation every year. She and Dad drove all over the place. She would spend that week in the car making her yo-yos then add them to her previous year's work. So a full sized quilt was finally finished after 15 years! Haha!
