Postboxes across Camberwell, Herne Hill, Dulwich and Crystal Palace have been struck by a yarn bomber with dashing knitted toppers and fluffy accessories since last autumn.
From baby blue octopuses to acid house smiley faces, (and everything in between), their creative genius knows no bounds.
This is the work of an anonymous Instagrammer, @postboxhappy, who uses the social media platform to share their antics with more than 1,000 loyal followers.
The yarn bandit’s targets suggest that they are from the area, plus one has the sneaky suspicion they might be a Dulwich Hamlet fan.
“This made us smile, thank you for creating such a joyous thing,” said one follower.
But it is not just south London that’s being targeted. The yarn bomber’s handy work has been spotted as far as Portsmouth and Warrington.
“We’ve just moved house and now walk past this little dude everyday,” wrote one follower. “My 1.5 year old is so delighted with him, we spend the rest of our walks saying “knit knit knit” every time we walk past postboxes in the hopes that we’ll find another one of your creations.”
“We’re on the hunt,” they added.
