Yarn bombers brighten Sarnia-area trees

Some trees in a small town near Sarnia, Ont., are creating quite a buzz after residents woke up to find a dozen trunks wrapped in wool-crocheted blankets.

It appears to be part of a North American movement called "yarn bombing," a concept to get people talking about improving sterile-looking public spaces.  

Mary Hoyles, the branch manager of a Sombra, Ont., bank said she found the crochet graffiti in at least 10 different spots around town.

"It would take three people — two people to hold it against the tree and one person to whipstitch it to the tree," Hoyles said. "That's quite a feat to be able to do that and nobody see them do it."

The curator at the Sombra museum has said yarn-bombing is akin to a public art installation.
