Quacking Christmas Cards

Did you receive a quacking Christmas card this year? If you did, were you able to guess the song? Each card is a different traditional Christmas song. (tip: the image is a hint to the song!) If you'd like to play along, enter your guess below, along with the number of the card (1-6). I'll randomly draw from the correct answers and the winner will receive a free set of note cards featuring some of my pastel paintings. Contest ends 1/1/23. (I'll also post the answers so you don't spend all of next year quacking away!)

Thanks for playing and Merry Christmas!
