Mulan’s postcard captures her design process for making her daily morning latte. She uses a pour-over method, which has many different steps and takes a considerable amount of time to brew the coffee. Reading from the bottom to the top of the postcard, the different layers of the coffee represent the steps that she takes in the coffee-making process. The volume that each layer takes up represents how long the step takes. See the back of the postcard for the key and other details!
