This morning, I was walking slowly and noticed there were calling cards attached. These yarnbombs are made by someone who calls herself MJ, who says she is "brightening the world, one yarnbomb at a time" and then she has an emoticon of :) a smiley face.
I think they are a hoot. They are found on several of the poles around here. When I went to her website, it has a FAQ sidebar with this:
Why yarnbomb, you may ask.
I do it to make you smile. It makes the world we live in a little bit brighter!!
