Christmas cards for your sister-in-law
A sister-in-law sits in an interesting spot. She is not quite family and not quite a friend, and she knows exactly what your partner was like at twelve. She can be your ally at the long Christmas lunch, or the person who raises one eyebrow when you reach for the third helping. Usually she is both.
A card to her works best when it sounds like the conversation you two actually have. Thank her for the group chat rescue, the quiet word in the kitchen, the time she took your side about the seating plan. Mention something only the two of you would know. Pick a card, add your words, and send the link by email or text, or schedule it for Christmas morning.

Questions people ask
What do you write in a Christmas card for a sister-in-law?
Write it the way you would speak to her. Thank her for something real, mention a shared joke or memory, and say you are looking forward to seeing her. A sister-in-law usually prefers warm and slightly cheeky to formal, so let your normal voice come through.
Do I need to send a card to my sister-in-law if we are not close?
It is a kind gesture and rarely goes unnoticed. A short, friendly card with a line about hoping to catch up is plenty. It can also be a gentle way to start getting closer, without needing to make a speech or plan a catch-up.
Can I send a sister-in-law a card that is a little bit cheeky?
If you already tease each other, yes. Keep it affectionate, aim it at yourself or something harmless like the board game rivalry, and avoid anything about her family or her choices. A little warmth under the joke matters.
