It’s a little bit early to go all out for Christmas, but I think all rules are off for 2020. If putting up Christmas decor on Halloween is your thing, DO IT!
Or if you want to subtly ease into the Holiday season, free artwork that you can easily print at home and swap out with frames you already have is a great starting point. It adds just the right amount of Holiday cheer!
I found all of these images by searching Creative Commons for “Public Domain Artworks”, browse the Met for “Open Access”, the National Gallery of Art, Indianapolis Museum of Art and The Rijks Museum. They are all high resolution and completely free to use.
