I cut out mitten shapes from paper and they decorated them with buttons and large sequence. Pom-poms would also work nicely.
I put some shaving cream on some paper to look like snow and let the kids finger paint with it. Some really love this, and other do not like to get their hands messy, but it is always fun to watch their reaction.
The kids painted white on a black piece of paper. The little ones love to paint.
After the paint dried, I cut the paper into the shape of mittens. Some large and some small, depending on the amount they painted.
We did not make this this year, but I thought this project would also work with this book. I painted the mittens and made their hand prints inside the mittens.
