Creative Phone Case Sticker Task List Prompts: Nope, Maybe, Someday

Create a set of vector-based phone case stickers illustrating a task list with categories: [Nope], [Maybe], [Someday]. Emphasize a clean, high contrast style with no shading or gradients, featuring simple line art on a pure white background. Each sticker should have space for customizable text inside clearly defined areas, with option for icons or visual cues to distinguish categories. Perfect for die-cut sticker formats, these designs should be straightforward, modern, and easily adaptable for printing, with variations in layout, label styles, and icon use.
