Yarn bombing and guerrilla knitting - who are SOCK?
A team of masked women arrived at day break.
Armed with crochet needles and scissors, they weave their woolly magic on the promenade in Newcastle, County Down.
Together they sewed woollen panels over pieces of public art, fences, benches and even tree trunks.
The women are part of an international trend called yarn bombing that has spread around the world in the last decade.
BBC Newsline's district reporter Francis Gorman caught SOCK in the act.
