SHE has tagged the Louvre, she has wrapped up Washington, she has crocheted London's Soho, not to mention Seattle, New York and Hollywood. Now it is time for Magda Sayeg, guerilla knitter, to stitch up Sydney.

"I don't care if I get arrested. There is no freakin' way that I'm leaving this city without tagging something big," Sayeg says.

Sayeg, 35, from Texas, is the founder of Knitta Please, a not-so-bad-assed posse of underground knitters who have made a name "yarn bombing" public spaces, graffiti style, wrapping their targets in brightly knitted "tags". In Canberra to host a festival of knitting linked to the National Gallery's "Soft Sculpture" exhibition, Sayeg believes there are few things in this world, from lamp-posts and parking metres to the Great Wall of China, that do not benefit from "a well-executed purl stitch".
