Calling itself the Micro-Fiber Militia, a group of crocheters in Chicago are following in the footsteps of groups like Knitta Please and the Knitta Crew, covering tree trunks, scaffolding, bike racks, and bus-stop poles with crocheted flowers and other colorful designs. One new group of works makes use of glow-in-the-dark yarn. Is it vandalism or graffiti of some type? The group's founder prefers to call it "artistic littering." [Methods Reporter]
