Granny Graffiti Stitches Up London

A band of graffiti knitters has been let loose and is currently stitching up London. Showing knitting isn't just about your grandma's tasteless jumpers at Christmas - the granny graffiti artists are warming up mundane objects throughout the city, decorating them with brightly coloured, spun yarns.

Any of you Londoners seen it for yourself? 

I for one love it - get your knit on!
