The central lending library hosts a 2-hour “knit-and-natter” on Wednesday afternoons as part of Edinburgh’s Warm and Welcoming policy complete with free knitting needles, wool, tea, biscuits and librarians happy to teach you to cast off.  There was more knitting than nattering until a couple of fellas turned up who were trying to stay away from a different kind of needle, the sort that took them to dark, lost places.
