The claim that social practices have a relatively durable existence in space and time, and that their persistence depends upon their recurrent reproduction through necessarily localised performances is theoretically plausible, but what of the detail? How do the careers of practices and those who “carry” them actually intersect? In this paper we have two related ambitions. One is to show how selected practices are concurrently shaped by the ebb and flow of recruits and defectors and by what it is that cohorts of practitioners actually do. The second is to learn more about the relation between recruitment and reproduction by comparing the ways in which these processes play out in different situations. In taking these two ambitions forward through a discussion of digital and film photography and of floorball (a team game in which players use plastic sticks to hit a small ball into a goal) we explore ways of concretely examining processes that are implied in Giddens’ theory of structuration (1984) and in Bourdieu's concept of habitus (1984). This exercise generates insights into the internal dynamics of practice and the methodological challenges of pinning them down.
