As Guenther and Hillit pointed out at Oldenburg Knit Night this week,
the yarn guerillas around the campus are still very active!
Favourite spots seem to be benches and (lamp) posts.
Still no signs of identification of the knitting guerillas and what their intention is. But despite their message Vera thinks knitting graffiti is a very good way to get rid of excess yarn.
PS: More Oldenburg yarn graffiti discovered by Annkari here.
