Professional practice in health and social care is embodied by the practitioners concerned, embedded in practice contexts and creative in nature. It is therefore complex to investigate, understand and develop. Current health and social care contexts can present practitioners with increasingly constraining circumstances and spaces that can feel closed instead of open to exploration and development of practice. The collaborative, critical and creative inquiry methodology presented here was developed among nurses practising in such challenging circumstances. It enables nurses and other health and social care practitioners to reveal, explore and develop their embodied practices, systematically and collaboratively, amid busy daily practice situations. However 'small' the space they are in, the process described here can help practitioners to enlarge their space for becoming. The iterative cycle and the use of participatory arts help illuminate otherwise hidden and difficult to articulate aspects of practice, enable the involvement of stakeholders in coming to new understandings and lead to an expanded view of professional practice and its potential for transformation. The purpose of this paper is threefold. First, to present the methodology, methods and lessons learned during the doctoral study in which this approach was developed. Second, to reveal the professional artistry of facilitating this space for becoming and of supporting professionals to reveal their own and others' professional artistry. Lastly, to offer inspiration and a guide for others considering similar participative inquiry work and to encourage debate and critique of the approach taken.
