Great way to say, "Thank you SNOW much for sharing your child with me each day!" and also for any Christmas gift you receive from a student. I took pictures mounted each child to card stock and will send home as my thank you note around the holidays.
Use card stock and misc buttons to make your own Christmas cards. The card stock can be bought at Walmart, etc. or at most any craft store. The buttons come in bags at most craft, hobby, or fabric stores.
