Everything's better wrapped in a sweater. Gap's spreading the joy one stitch at a time with "knit bombing;" a new style of street art that wraps everyday objects in knitted cloth. Gap's Knit It Up campaign brought holiday cheer to winter trees and park benches by creating art installations with a warm, and light-hearted feel. Check out the behind-the-scenes video to see how Gap turned their photo shoot into a joyous occasion with plenty of knit bombing and a bit of snow.
