In addition to 25 vintage, antique, handmade, and food vendors, our newest location at PS 321 in Park Slope also features free programming for kids of all ages courtesy of some of the finest youth organizations in Brooklyn. Stop by every weekend between Noon and 3pm and participate in mini-book-writing workshops by 826NYC, dance lessons by Mark Morris Dance Center, physics experiments by Carmelo the Science Fellow, recitals by Brooklyn Conservatory of Music students, and filmmaking by Reel Works. All activities are free.
