Doily bombed

It has happened again. Only this time, the campus has not been yarn bombed, it has been doily bombed! I am not sure if this is more serious than yarn bombing or if one reads a lighter sense of play into this format.  
As you can see, the lampposts along the walkway have all been 'doilied'. Note the yellow 'comment' card that has been attached to each doily bomb, along with a pencil to capture your thoughts.
I Googled doily bombing and was surprised to find other locations where this deed has taken place. This picture of a doilied tree shows a beautiful collection of vintage doilies gracing the tree like a lace glove.
Further Googling brought up a BBC new segment which may provide a hint of how yarn bombing came to Canada. At around the 1minute 40 mark, two seemingly innocent looking women from Vancouver are interviewed and state that they will take this new knitting trend back to the west coast of Canada. Have we found the guilty importers referred to in my earlier post?
