They’ve been knitting for a month or two, now, in cafes and bars and on park benches, but over the weekend the assembled thread wound its way around Kings Cross.

Centred on Fitzroy Gardens, and the beautiful El Alamein fountain, but extending a little way along Macleay Street and Darlinghurst Road, it’s a project called I Heart Kings Cross, and it’s part of the council’s Art & About program.

The guys behind it, Reef Knot, formed out of the ashes of Knot Gallery four years ago, where the crew had collaborated with designers, musicians, sculptors and painters to create installations for street, art and music festivals.

Inspired by the work of Newtown’s Denise Litchfield, Texas’s Knitta Please, and Stockholm’s Maskerade, they’ve tackled this massive knitting project.

Collectives are springing up all over the place to knit in public places. It’s being called guerrilla knitting, and I reckon its roots are in guerrilla gardening. It’s a little bit political, and a lot about creating sections of spontaneous beauty in sometimes tired neighbourhoods.

We don’t usually post so many pictures, but this is really just spectacular, and every single bit of knitting is worth seeing. We started to feel a little sorry for the trees without woollen cloaks, especially with the current cold snap.

Walking through Taylor Square on Sunday afternoon, we noticed this.

Denise Litchfield, of Newtown, had descended on the old below-ground toilet the night before with a cast of “lavatory assistants, urban knitters and crocheters.”

It’s Sydney’s last surviving underground toilet (not including those in train stations) – it’s a convenience that’s not that convenient, because it’s not open – though it gets a last gasp every now and again via an art project like this.

Denise, who also blogs here, knitted this as part of Sydney Design 09.
