It is a new trend of knitters getting together and knitting things around public property. The groupe in Stockholm is called Masquerade . There is also a famous guerilla knitting crew in Texas www.knittaplease.com
A tag crew of knitters, bombing the inner city with vibrant, stitched works of art, wrapped around everything from public monuments, utility poles and all what they feel. So the Masquerade´girls, if you come to Svartmangatan 10, exprime yourself you are more than welcome!
The Bobo advice : During the week-end, enjoy yourself following their mapp and see Stockholm in a different way!!!
and of course they travel!!!
