As lead-up to the Humboldt County Library's Harry Potter Celebration, a S.P.E.W.-themed knitting class will take place from 4:30 to 5:30 p.m. on Wednesday, Oct. 26. Hermione learned to knit in order to benefit the House Elves, and so can you! The class will be taught by Sunni, the owner of Yarn in Henderson Center. Yarn will be provided; however, knitting needles are limited so please bring your own size 9, 10 or 10.5 needles. Class size is limited to 10 participants ages 10-16, so please call to reserve your spot.
