Collection is an important activity and marker of childhood. In this article I will discuss Pinterest as an online iteration of the collection process. Through Pinterest, users amass bits of information online, known as pins, to display on virtual bulletin boards. My project positions Pinterest as an influential text and literacy practice related to identity production with particular impact on girls. With obvious parallels to the keeping of commonplace books, Pinterest is an act of virtual curation that shapes a pinner's present and future identities. In the Pinterest space, girls see and collect ideals of femininity (displayed in recipes, fantasy weddings, and parenting tips) and in so doing create their own online avatars. This practice requires a critical awareness as users reinscribe, resist, or reinforce cultural norms of femininity. This article offers a conceptual base for future systematic study of Pinterest as a text and practice of girlhood.
