For years, the trend Up North has been to shirk anything fussy and pare down to the calmest elements. But now it’s time to mix it up. A lace doily atop a period chair that is flanked by low-slung modern sectionals, peut-être? Or, maybe it’s a traditional lacy dust ruffle peeking out from under a toasty quilt—stitched from bold, abstract shapes. To shop for these lace accents (turn off your tablet) and cruise our village antique shops, estate sales, flea markets and country auctions.
