As part of her holiday preparations, Cathy decorates sugar cubes. Cathy's aunt, Ms. Betty, runs a bakery and likes to think of ways to make her store more attractive, especially for holidays. She enjoys cutting, arranging, and designing seasonal displays with her famous brownies almost as much as she enjoys baking them. And everyone loves the different sizes of Ms. Kate's chocolate sticks.
