I No asked people what it is in their lives they would like to be able to say no to, but have difficulty doing so. Participants were asked to share their answer by adding it to the guest book, telling me personally, or in another version, providing their "No" in a collage of Post-It notes. After the exchange, I offered people a pin that stated one of three sayings: "I NO", "I'm a Nay-Sayer", and "NO-ing is Believing".
