"all my knittas in the house..."

These weird women from Houston have a pseudo-graffiti problem. Mainly, they are the problem, and their knitting is the pseudo-graffiti. They take their knitted pieces and attach them to poles, railings and other public things so that it looks like it was knitted onto the object. I think they must pre-knit the pieces and then just sew up the tube with yarn or something. What will people think of next? Quilting Bee Terror Cells?
