• Family Photos: Incorporate a favorite family photo or a picture of a special moment you’ve shared.
• Inside Jokes: If you have a playful relationship, include a reference to a shared joke or a fun memory.

5. Choose the Right Medium

Think about how you’ll be sharing the image. The medium can influence the style and design you choose.

• Text Messages: If you’re sending it via text, keep it simple and easy to view on a phone screen.
• Social Media: For platforms like Facebook or Instagram, go for a bold, colorful design that grabs attention. Pair it with a heartfelt caption to make it even more meaningful.
