An anonymous Wollongong yarn bomber has struck again, with a trio of circular bike racks in Keiraville the latest public objects to receive the woolly treatment.
The unauthorised textile street art is the work of a crafty 76-year-old grandmother who moved to Wollongong about three years ago and just wanted to spread a little joy.
"I started a knitting group at the library (in my old town), and I'd been doing silly things like this and everyone else was terribly serious," she said.
"They all thought 'knit for charity', which is really, really nice, but really, really boring.
"So I got a couple of the girls together and used to yarnbomb just one little street where there's a whole lot of coffee shops and everyone seemed to absolutely love it."

Jessica Ruiz of the The Giddy Goat, located next door to the playful new instalments, is also a fan.
"I like them, they bring colour to the community," she said, adding they had become a talking point with customers.
The mystery yarn bomber's first project in Wollongong was a row of crochet caps atop posts outside the library on Burelli Street, all free for the taking and gone before the day was out.
Next up she has her sights set on the metal handrails at North Beach.
"There's those long flights of stairs," she said.
"If we anchored it really well and covered the handrails - because they get really hot and they get really cold - I would just love that to happen.
"It just adds a bit of colour and people smile. It's all done for a laugh really and if I can find some more people to do it and join in we'll do more."
