While the major fashion houses are turning out grandma-style sweaters, ponchos, and woolly bags this season, some knits really are being made by grandparents. Dorothy Gleaves, the 61-year-old Tennessee aunt of downtown designer Leigh Anne Fitzpatrick, helps out with the knitting chores for Fitzpatrick’s line of angora-and-merino cloches ($88, available at Dressing Room and TG-170). Seventy-four-year-old Ralph Miller, a former steel-mill worker who lives in rural Pennsylvania, crochets to relieve his arthritic hands. His kooky, multicolored line, Uncle Ralph’s Ugly Hats, sells exclusively at TG-170 ($44). “It’s how I relax,” explains Ralph over the phone. “I watch football and crochet.”
