The NYC Yarn Crawl is this weekend -- an annual fall extravaganza in which fiber craft lovers off all kinds visit knitting stores across Manhattan and Brooklyn. There are events! Discounts! Scavenger hunts! And the opportunity to "touch, squeeze and sniff all the latest yarns," all while in community with fellow knitters. Kiana Malekzadeh, owner of West Village Knit and Needle, one of the stores on the Crawl previews the event.
