I have to admit I am terrible at sending out thank you cards after Christmas. Half the time it is end January before I do them *shamed*
This year I saw in the shops some thank you cards for kids and knew I wanted to design my own. And I thought they would make a great final addition to my advent calendar.
I designed two sets that are available for download. You get two letters per sheet of paper. Simply print at 100% scale and trim down.
I also have other thank you card printables in my etsy shop, including ones like this where you can design the character and colour scheme.
