Thank you to Perri at the Guardian for alerting us to the fact that MAGDA of KNITTA fame, has arrived in London to-day and is up for a bit of guerilla graffiti knitting action. Not knowing any knitters here, she has invited us all to meet her today outside the Royal Festival Hall (Friday 20th February) at 10am which I'm sorry to say is a few hours ago - I thought she said pm duhh.. 
Magda and her friends from Texas have shot to world wide fame by tagging public places with beautiful pieces of knitting, covering up ugly fittings, cheering up boring places and making art in spacial places. 
If you are having a walk down the South Bank this weekend, have a look, and why not try a bit of knitted graffiti yourself!
