Jack Frost, artist
Frost patterns were plenty common on our storm doors when I was a kid in Minnesota but I hadn't seen them in years. They reminded me of how I used to borrow my mom's thimble and make pictures on the frosted windows, because that's what Laura and Mary used to do in the wintertime. Which got me to wondering, what book was that in, anyway? Little House in the Big Woods? Or Long Winter. Googling took me to this wonderful frost photo, and my answer!
