Peel potatoes and place them in a large pot with a large amount of water. Bring water to a boil, and let the potatoes boil until soft. Drain and mash well.

In a large mixing bowl, combine 8 cups mashed potatoes, cream, butter, salt, and sugar. Cover potatoes and refrigerate until cold or overnight.

Mix flour into the mashed potatoes and roll the mixture into balls about the size of tennis balls, or smaller depending on preference. Keep balls of dough on plate in the refrigerator. It is important that dough balls stay cold till they are rolled out.

Taking one ball out of the refrigerator at a time, roll dough balls out on a floured board. To keep the dough from sticking while rolling it out, it helps to have a rolling pin with a cotton rolling pin covers.
