Whoops! You decided to make a sewing project that requires the zipper, a device created 133 years ago to make the wearer’s life easier and the sewist’s life difficult. No worries, though, because your trusty local library’s Fix-It Clinic has a workshop totally focused on those metal teeth. In this hour-and-a-half class, the beginner and expert alike can learn special zipper skills – as long as they already know how to use a sewing machine. Never fear the zip again! – James Scott
