This article examines the composing practices of two members of a social sorority who use visual images on the media of Tumblr and YouTube to teach potential new members about the kind of sorority experience they will have. From interviews with these composers and analyses of the artifacts they create, I distill three composing principles used to create the sorority's collective public image: be cool, stick to a vibe, and be exciting and unexpected. I connect these strengths in visual composing to existing scholarship in writing-across-the curriculum and writing-in-the-disciplines (WAC/WID) and identify areas where WAC/WID instructors might provide more scaffolding for students in the visual composing process.
