Armed with needles and a yarn of wool, a dozen knitting aficionados have danced to deafening heavy metal music while knitting during an unusual competition in Finland.

The goal of the Heavy Metal Knitting World Championship, which took place on Thursday, was quite simple, to showcase knitting skills while dancing to heavy metal music in the most outlandish way possible.

Performers had stage names including Woolfumes, Bunny Bandit and 9″ Needles, and they swirled their hair to the fast-paced rhythm of the music.

The competition took place in a packed square in the small town of Joensuu close to the Russian border.

Some 200 people gathered to watch the performances, including families with children and heavy metal fans donning leather-jackets.
