I watched a Ted Talk recently about a worldwide movement called "Yarn Bombing" I had never heard of.  It seems to be all around the world and takes a lot of work to make their "bombs"! What do you think? Cool and creative or annoying? https://embed.ted.com/talks/magda_sayeg_how_yarn_bombing_grew_into_a_worldwide_movement   d1a4c498181d710c031a86782f6d290bc3f71d85b54651634e
