Rope, balls and a new seating arrangement have popped up at Bayfair mall thanks to the latest challenge taken on by the Ninja Knits.
The group, which has been behind other public knitting challenges such as yarn-bombing the Strand, took on a slightly different creation this week.
With the help of the public, they have started on a long, snake-like knitted seat, as part of Saturday's World-Wide Knit in Public Day.
Ninja knitter Wendy Pedersen said their project was similar to French knitting, which uses a cylindrical device which the material is wound around to create a tube of fabric out the bottom.
"It's an interactive public art installation. The kids love it."
