Create a collage design for a couple's milestone anniversary celebration. 1. **Layout**: Use a symmetrical grid layout with multiple rectangular frames for photos, arranged in a mix of larger and smaller sizes. 2. **Photos**: Include four to six images capturing happy moments together—these can be outdoor scenes, events, or candid shots. Make sure the subjects are casual and joyful. 3. **Background**: Use a soft, pastel-colored background with a subtle texture. Add decorative elements like light sparkles or floral patterns. 4. **Text**: Feature a large, elegant heading saying "Happy Anniversary" at the top, and underneath that, in a playful font, include "Cheers to 40 Years!" Ensure the text is in contrasting colors to stand out. 5. **Graphics**: Add small hearts or confetti around the text for a festive touch. 6. **Borders**: Use a thin, decorative border around the collage for a refined finish. Choose a color that complements the overall color scheme. 7. **Remove Brand References**: Ensure that there are no logos, names, or identifiable brand elements in the design. This design concept should be celebratory and personal, emphasizing the couple's journey together.
