FAQs
What do you write in a sweet 16 card?
Write something warm, personal, and encouraging. Start by acknowledging the milestone — turning 16 is a genuine coming-of-age moment.

Even one specific detail makes a huge difference.
What to write in a teenage card?
Teenage card messages work best when they feel real — not lecture-y or overly sentimental. Match the tone to your relationship. For a teen you’re close to, be warm and a little funny. For a teenager you’re less familiar with, keep it encouraging and genuine. Focus on who they are and who they’re becoming — not just the number.
