This is seriously some of the coolest scaffolding I’ve ever encountered. I was walking down Mariahilfer when I saw it, and my friend said it’s actually a phenomenon called ‘guerrilla knitting.’ Turns out, it has many names!
According to Wikipedia, it’s called Yarn bombing, yarnbombing, yarnstorming, guerrilla knitting, urban knitting or graffiti knitting, and is a type of graffiti or street art that employs colorful displays of knitted or crocheted yarn or fibre rather than paint or chalk.
While yarn installations – called yarn bombs or yarnstorms – may last for years, they are considered non-permanent, and, unlike other forms of graffiti, can be easily removed if necessary. Nonetheless, the practice is still technically illegal in some jurisdictions, though it is not often prosecuted vigorously.
While other forms of graffiti may be expressive, decorative, territorial, socio-political commentary, advertising or vandalism, yarn bombing was initially almost exclusively about reclaiming and personalizing sterile or cold public places. It has since developed with groups graffiti knitting and crocheting worldwide, each with their own agendas and public graffiti knitting projects being run.
So there you have it. Yarn bombing! 
It is such fun, isn’t it? Just today my cousin posted some pictures on Facebook of similar things in Cambridge!
Fantastic
Nice. We have a bunch of it down the bottom of the village shopping area here. On lower poles, so slightly less ‘extreme sport’ bombing to your example!
Cool – take some photos!
Is that what you call it… I saw some lamp posts in Napier (NZ) last year with cute and colourful woollen coverings. Good to know!
Haha, first time I’ve ever seen this! I think it’s a marvellous idea though!
If I didn’t know any better I’d say you’d just discovered a new hobby.
Haha! I’d be totally keen on this! But I can’t say I have enough time for it.. and I do prefer knitting to keep people warm to knitting to make poles look pretty…
