Anyone that gives a gift or donated their time deserves to be acknowledged. Short and sweet, and to the point is ideal. Whether the cards are for wedding gifts, baby showers, birthdays, or notes of sympathy, the sentiments need to be sincere.
If you’re writing 20 thank you cards or just one, thank you note wording needs to be emotive and express your gratitude. People love to receive actual thank you notes. And handwritten ones give the impression of sincerity.
