Whimsical Girl Baking Line Art

Black-and-white line art for a children's coloring book. A young girl named Ella, around 6 years old, with long braids or curly hair in pigtails, wearing a cute apron with cookie patterns, a headband, and holiday slippers. She is cheerful, caring, and loves to bake and share with others. The style is whimsical and festive, with bold outlines and a pure white background. Include a thin-outline title at the top that says: "The Cookie Exchange" Scene: Ella trades treats with friends at a long table of baked goods.
