'I wanted to make them prettier': One artist's yarn lends color to south King County

The unincorporated and recently incorporated areas of King County near where artist Christy Caravaglio lives are the picture of the smaller American city.

"Near where I live, there are a lot of blank concrete walls," Christy said. "Like retaining walls and chain-link fences on the roads that I take to and from my house. I wanted to make them prettier."

Because of those big blanks walls, Christy's first thought was murals. But the process was intimidating. Then, she learned about "yarnbombing."

"People knit or crochet things, and they wrap anything you can think of — trees and posts and bicycles and busses," she said. "And more specifically, people do yarnbombing on chain-link fences."
