"All it cost me were pens and time," says Shantell Martin of her Brooklyn home and studio. From the baseboards to the ceiling, the space is inhabited with a hand-drawn mural by Martin herself. The best part is that his Brooklyn home and studio is actually rented! Martin says that her landlords are supportive of her scribbling habit, as long as it is limited to the top floor. And it's not just the walls -- vases, shirts, shoes, toys, and more are covered in the intricate designs.
