Bay seniors with time on their hands might consider holding knitting needles in them. The world of knitting has moved way beyond your grandmother’s antimicassers. Check out a hip shop called A Verb for Keeping Warm [what were they smoking when they came up with that name?] located in yet another unexpectedly gentrifying Oakland neighborhood. Short of sheering your own sheep you’ll find everything here – a rainbow of yarns, classes in spinning, weaving, felting, even growing your own dye plants. If you don’t need to make a new winter scarf, consider knitbombing something.
