Creatief met Clowns is a creative and art-based workshop for people living with dementia that invites participants to join in a collaborative process of creating an outfit and clothing a clown. In this article, I look at what happened in workshop sessions and how this mattered to those involved, including what participants with dementia valued about the activity - by listening to what they had to say, but also by attending to their performative, creative and affective ways of engaging in Creatief met Clowns. To further articulate values that came up in practice, I analyzed my findings in terms of the quality of psychosocial relations, the role of embodiment, material aspects, and playfulness in person-centered care. By combining an ethnographic study of art-based care-practice with a value-sensitive theoretical reflection on empirical findings, my approach offers an alternative to problematic efforts to quantify the value of art in person-centered dementia care.
