Karen Stohlman is one of the best friends of Maryellen Larkin.
Personality
Karen has long brown hair. She is a ballerina. She likes for everything and everyone to be the same and the girls to match most of the time, if not all the time. She usually has brand-new clothes, as her only sibling is an older brother and so new clothes can be purchased for her. Karen considers her brother--and all boys except Davy--to be a pain.
Karen lives in a different neighborhood than Maryellen but she sees her at school and is in the same Girl Scouts Troop (until Maryellen stops to be part of the Science Club).
