Those Swedes are a crafty bunch. Instead of decorating the streets of Stockholm with graffiti art, they turned to illegal street knitting, or "craftism."

It all started with a guerrilla crafting group called Masquerade, who at first seem hell-bent on "tagging" all of Stockholm with these funky, colorful knitted bands, but have recently turned their needles on the entire world. A quick trip to their blog reveals their nefarious antics in LA, San Francisco -- even Indiana!

In addition to spreading joy by adding fuzzy spots of color to urban landscapes 'round the globe, these derelict crafters also like to embroider messages into the cloth seats of commuter trains -- like "kram," which translates as "hug."

So join the movement! Pick up some yarn, and stick it to the man -- with a knitting a needle!
