I had seen the work of Kelsey Montague about a year ago. I love her idea that her murals are interactive and that people can post themselves with the art to social media.
My students did self-portraits in oil pastel then cut them out and affixed them to wings of their own design.
We took it one step further and several students contributed to create a mural that students can interact with. It has been a big hit with kids and adults alike.
