Young Mary Ellen and her mother don't know it yet, but the doll they create from scraps of fabric will become a very special family friend. Mary Ellen names the doll Betty, and Betty accompanies Mary Ellen through every family crisis and celebration --- and all the important milestones in her life. Betty has become so treasured, Mary Ellen wants to make sure that the doll will always be loved --- even when Mary Ellen is no longer alive. That's why when Mary Ellen is older and ailing, she writes a letter to her own daughter Tricia (Patricia Polacco) and packs it away with Betty in the attic. The tender story of Polacco's discovery of the doll and the letter will touch your heart.
