The study examinesthe variety of interaction and motivation practices to participate in the sharing initiative as well as pinpointing key elements of member-driven organization functioning;in the case of Stockholm Makerspace– a community of non-professional makers.  The Current scholarship on sharing is mostly focused on the large-scale platform businesses in a North American context, thus evidence from grassroots small-scale initiatives is lacking. This paper aims to fill this gap by providing the empirically grounded sociological study of the operation of sharing initiative in Sweden. Data including 1) 11 in-depth interviews conducted with active members of the community and experts, 2) ethnographic observation in situations of planned workshops and everyday life of the Makerspace, 3) systematic online observation (in the role of observer as participant) (Gold, 1958). Therefore, this study employs mixed ethnography and digital methodology – studying sharing economy communities both online and in situto provide a ‘thick’ description of community building. The results revealed that members of the Stockholm Makerspace, acted as prosumers, and attempted to benefit not only from the community understudy, but also contributed to the societal development at large, by creating a public good. Shared access to tools and common “know-how” democratized production of knowledge and its spreading, thus contributing to informal learning, which complemented formal education institutions. The main incentives of sharing, vocalized by participants in the study were open-ended socializing and community commitment, as well as self-expression and belonging.
