Boulder artist and University of Colorado Boulder instructor Steven Frost is a disciple of Carol Frances Lung, aka Frau Fiber, whose Sewing Rebellion movement invites people to commemorate sweat-shop laborers and their essential work through sewing projects. Frost, an official "Faux Frau," carries on Lung's mission locally by mentoring free monthly DIY sewing workshops at the Boulder Public Library's BLDG 61 Makerspace, where he encourages participants to upcycle used materials in creating everything from bike caps to Halloween costumes.
