yarn bombing in Prague and Boston

Here are two knit cozies I spotted wrapped around a street lamp in Prague and a tree in Boston. "Yarn bombing," as this form of graffiti is called, is apparently quite a big thing now in the world of street art. There's even a wikipedia page. Proponents of yarn bombing claim to be softening and feminizing urban space with their work. At the very least, they're helping some street furniture stay warm.
