Questions

What do you write in a Father's Day card for your father-in-law?

A Father's Day card for your father-in-law thanks him for the person he raised — and the welcome that followed. The strongest messages name one specific, true thing about them and say plainly how you feel — keep it short and it lands harder.

How long should a Father's Day message be?

One to three sentences is plenty. A short, specific line beats a long, generic paragraph — people remember the detail, not the word count.
