Here is a simple thank you note template for wedding gifts.
Dearest [name]
We were really surprised with the thoughtful gift you gave to us at our wedding. We didn’t expect such a wonderful gift. You shouldn’t have made an effort but since you did, thank you!
Thank you for coming to our wedding and hope you had a great time. It has been a long time since we saw each other so it was great to catch up.
Sincerely,
