Knit the City: A Whodunnknit Set in London. Deadly Knitshade

You may have heard of guerrilla gardeners... Now prepare to meet your friendly neighbourhood guerrilla knitters, whose prime objective is to enliven dull city streets with a riot of colour - one stitch at a time. These creative knitting ninjas transformed a ballerina outside the Royal Opera House with their woolly works of art and installed a 13 ft spider's web, replete with trapped insects and fairies, in a tunnel beneath Waterloo station. The stunning photographs of their exquisite feats in Knit the City will ensure that you never see knitting - or London - in the same way again.
