The Mystery Project

What happens when you make a stranger's day?

This week's final free project in the 10 x 10 Series is a collaboration with our friends at Prismacolor. The Mystery Project challenges artists to experiment with the unexpected. Every participant will receive a mystery project kit, which includes a free Prismacolor Brush l Fine Art Marker in a surprise color and a secret theme to guide your work. Create a token of inspiration using the tools in your kit — it could be a drawing, a zine, a sculpture, or a collage — then install it in a public place for a stranger to discover. Just remember to document your mystery project and send us a photograph! We'll share your creative surprises with the entire community online.
