Messages for Different Relationships

The relationship you have with the person will shape your message. Here are some tailored ideas for different family members.

Crafting a Personalized and Memorable Card

To make the card truly special, go beyond just a message. Here are some creative ways to personalize your birthday card.

Include a Group Message: Have other family members and close friends add their own short notes or signatures. This creates a collage of love and shows the breadth of their influence.
Add a Photo: Include a cherished old photo of the two of you, or a collage of photos from different eras of their life. This visual element can evoke powerful emotions.
Write a Poem or Song Lyrics: If you have a talent for writing or they have a favorite song, a short poem or lyrics can add a very personal and touching touch.
Use a Life Milestones Table: Create a small table inside the card listing some of the major milestones in their life, such as their birth year, major historical events that happened in their lifetime, and key family dates. This provides a fun, reflective look back.

Frequently Asked Questions

If you don't know the person well, keep your message warm, respectful, and slightly formal. A simple, sincere note is best. For example: 'Wishing you a joyful 90th birthday and many blessings in the years ahead.' or 'It is an honor to help celebrate this incredible milestone with you.'

Humor is perfectly fine, but it should be used cautiously. Ensure the jokes are gentle and align with the person's personality. If you're unsure, it's safer to stick to a heartfelt or respectful message. Avoid jokes that focus on frailty or memory loss.

The length of your message depends on your relationship with the person. A few heartfelt sentences are often more powerful than a long, rambling paragraph. Focus on quality over quantity. If you have a close relationship and many memories, a longer note reflecting on your shared history would be appropriate.

Start with a warm greeting that acknowledges the milestone, such as 'Happy 90th Birthday!' or 'Congratulations on this amazing milestone!' End with a sincere closing, such as 'With love,' 'Warmly,' or 'Gratefully,' followed by your name.

You can pass the card around during a family gathering so everyone can write a short note. Alternatively, collect messages from family members in advance and write them all inside, or even create a special booklet of messages to include with the card.

Write in large, clear, and dark handwriting. Use a black felt-tip pen or marker rather than a ballpoint pen. If your handwriting is naturally small, consider typing and printing your message on a nice piece of paper to insert into the card.

Yes, referencing their age acknowledges the significance of the milestone. You can do so respectfully, focusing on the achievement, wisdom, and resilience that come with turning 90, rather than focusing on the number itself.
