Yonkers Pottery Studio is one of a handful of new establishments in Westchester that caters to adults who like to get messy. Monday and Wednesday nights from 7 p.m. to 9 p.m. are reserved for an eight-week course where apprehensive adults learn the basics of pottery making and sitting at a wheel. The studio also hosts an introductory, adults-only clay soiree on the third Friday of each month for those not ready to commit to an eight-week intensive.
