Bridget is an artist. But she has lost her beret and along with it, her inspiration and, she things, her abilities. When the younger girls coax her to help with the sign for her lemonade stand, Bridget is newly inspired and regains her confidence.
The part I found most fun was Bridget's interpretations of classic works of art in her lemonade stand advertisements. The author includes a section in the back on famous works of art.
