On a stretch of parkland flanking the Mapocho River which bisects Santiago, Chile, a quilt-like covering encircles the glistening trunk of a palm tree. Nearby, overlooked by the Museo Nacional de Bellas Artes
(Museum of Fine Art), wooden benches stand sheathed in geometric patterns woven from yarn.
They are a few of the public objects that have been "yarn-bombed" in recent months, as a movement known locally as intervenciónes textiles has inspired imaginations across the South American nation.
A far cry from the marble sculptures displayed in the nearby museum, the trend that began in Texas in 2005 has seen a growing number of open spaces transformed with woolly creations reminiscent of giant tea cozies.
Knitting: Not just for grannies anymore
The interventions may be little more than a whimsical fad to some, but to Claudy Tapia Retamal, who founded the yarn-bombing collective Lanapuerto
(wool port) in Coquimbo, a coastal town in northern Chile, it's a social project with far-reaching goals.
Tapia Retamal, who earns a living as a fashion designer, says she's trying to debunk outdated assumptions while drawing people into playing a more active role in their community.
"When I founded the group, the goal was to smash stereotypes," she says. "Knitting is no longer just for grannies. It's for women, men and children.
"We go to public places and we give a meaning to them through the designs and the colors. We don't knit boring patterns in bland colors. We yarn-bomb in green, red, purple. The idea isn't just to cover objects. It's to beautify them as well."

So far, the group has yarn-bombed a fishing boat, the control towers of two industrial cranes, several bicycles, and a large stretch of railing.
What inspired all this knitting? "We wanted to develop the port's identity and differentiate ourselves from other yarn-bombing groups which tend to focus mainly on covering trees," she explained. "As Lanapuerto is based in a port area, we wanted to focus on what characterizes the zone, like the sea and the port infrastructure. At the same time, we wanted to help make the work of the local fishermen here more visible."
The structures that proved most difficult were the control towers on the port's 98-foot industrial cranes. Since they were located on a private site, there were a number of health and safety rules to observe.
"Initially the port workers didn't understand what we wanted to do, but after a few days they got it and we were working as a team."

A few months ago, her team spent three months stitching a huge covering for a pedestrian railing along the seafront, using $325 worth of multicolored wool. That's a great deal of money in a town where the average monthly income is less than $972, but Tapia Retamal sees it as more than a way of passing her spare time.
"For me it's an enjoyable and enriching collective form of work. It's helped facilitate networks of friendship."
Enlivening the city
A few hundred miles south in Barrio Italia, a neighborhood historically inhabited by Italian immigrants in Santiago, a man's mountain bike saddle is being cushioned with a triangle of red and orange yarn. On plastic chairs a few feet away sit members of Lanaattack
(Wool Attack), a yarn-bombing collective that has made more than 30 interventions since its founding two years ago.
Today the group is yarn-bombing bicycle saddles, but next month they hope to "invade" several music festivals with their colorful fabrics. After that, says group member María José de Santiago, they hope to cover iconic monuments and "take over the world!".
The group's initial aim was to add color to Santiago, which they see as overwhelmingly gray. It's also become a way to make the public think about the way they relate to the spaces around them.
"Normally cities have an identity that is cold and distant. There can be a sense that you are there but you don't belong there," de Santiago said. "We wanted to change all that so people feel more connected and as if they belong ... Yarn-bombing is urban art, it's an expression of the people, and we want to cause a knitting revolution by taking this tradition and bringing it into the 21st century."

It's a bold ambition that has come with challenges. Displayed in open air, often in crowded places, the interventions can be used or abused by passersby at will. Both groups have seen their work torn off, sometimes minutes after being put up. On one occasion, a local took a lighter to the wool and set it on fire. But for the most part, the interventions last several weeks, and sometimes much longer.

The temporary nature of the art is particularly relevant for Wen Roh Lee, who combines yarn-bombing interventions with charity work through the club Tejiendo Juntos Chile
(Knitting Chile Together). The 31-year-old engineer covers palm trees and park benches during the day, before donating the creations to orphanages and homes for the elderly in the evening.
"I think of yarn-bombing as a form of self-expression, a way to give color and warmth to the city and to change the surroundings," she told CNN. "I want to provoke a reaction from people to see something different while they are going about their day."
But in a country famous for punctilious respect for the law, yarn bombers risk brushes with the local Carabineros (national police force). Without a permit to place yarn over public objects, they can be fined. And in Chile, even a minor criminal record can have catastrophic consequences for an individual's career prospects.
"We had a permit to yarn-bomb Parque Forestal a while back," de Santiago recalls, referring to one of the city's most popular park areas. "The people from the local council arrived very early asking us to show our papers. They told us: 'You can do only trees. You can't do lamp posts or benches.'
"If I have a message it is: 'Come On!,' she laughs, 'It's art! We're doing it to make people happy.' Hopefully later on, here in Chile, they can allow us to be more free."
In an environment where machine-made goods dominate and social interaction has become increasingly digitized, Chile's yarn-bombers offer a refreshing take on an ancient craft that harks back to a time when communities were, truly, closely knit.
As de Santiago says: "Sometimes just a little bit of change can bring about another change, and then another, until you have a chain of changes, and, when you think of it like that, it's a revolution."
