She worked for a time as Eva LaGalliene's stage manager before moving to Stony Point, New York, where with Cordelia Hamilton, she opened the Stony Point Folk Art Gallery in 1948. The gallery soon became known for its displays of folk sculpture, of which decoys were a particular highlight. Growing from this interest, Earnest in 1965 published The Art of the Decoy: American Bird Carving, among the first books to discuss decoys in a scholarly context.[1]

In 1984 she published a combination memoir-history of the field of folk art collecting, Folk Art in America: A Personal View.[1] Earnest traced her interest in the art of decoys to a set of three carvings of dovetailed geese which she purchased in 1954; two of these she sold to Stewart Gregory, and one has since been dubbed the Earnest-Gregory dovetailed goose.[3]
Death
She died in a nursing home in Mount Vernon, Washington. She was survived by her son, Eugene, and two grandchildren, her husband Joel having died many years before.[4] Earnest's papers are held in the archives of the American Folk Art Museum.[5]
