Do you live near a great fence? Is that fence in a park, or in front of a community center or shelter or food pantry? Is there a fence around your house of worship? Now that it's officially Fall, it's time to plan some scarf bombing. Ten years ago, scarves appeared around the necks of famous statues in Ottawa, Canada, on a chilly January day. Each scarf was tagged with a note that read: “I am not lost! If you are stuck out in the cold, take this scarf to keep warm.” It was later revealed that some university students were behind the good deed. The incident went viral, and is part of a movement now known as “scarf bombing” — leaving handmade scarves in public places to warm people up during the winter months. The scarves are typically tied around fences, benches and railings, and are especially intended to support those experiencing homelessness. In downtown Boston, where I live, there are areas in Boston Common where homeless men and woman congregate, but also where lots of tourists and students walk by. I'm going to start making scarves (they might be knit or crocheted, or cut from fleece) and tying them on fences near me. If you'd like to join me, please let me know.
