Rosemarie Jarski gained a thorough knowledge of how to launder lederhosen, polish a flugelhorn, fricassee frogs legs, and clean blood stains off a matador's pants while working her way through Europe as an au pair. After settling down in London, she has become an old hand at removing stains from anything, getting the musty smell out of a damp umbrella, carving a roast, and a plethora of other useful things everyone should know how to do. Milena Jarski trained as a graphic designer. She spent some years designing artworks for international ceramic companies, specializing in animal portraits. She now illustrates books. In her spare time, she loves to put on her tool belt and wield a high-performance drill.
