Cottagecore Mushroom and Book Vector Sticker Prompts

Create a series of clean, high-contrast vector illustrations focusing on cottagecore themes: mushrooms and books. Use minimal details, no shading or gradients, on a pure white background ideal for die-cut stickers. Incorporate placeholders like [MUSHROOM_TYPE], [BOOK_TITLE], and [ADDITIONAL_ELEMENT] for customization options, ensuring each design conveys rustic, vintage charm with bold outlines for crisp, attractive stickers.
