Overview Secondhand Saturdays closes a block of 37th Avenue in San Francisco's Outer Sunset on the third Saturday of each month from April to November and fills it with more than 60 vintage dealers, makers and artists, plus a garage-sale zone for the neighborhood. It runs 10 a.m. to 4 p.m. between Ortega and Pacheco streets. Sunset Mercantile, a Sunset District producer of markets and street festivals since 2014, runs it; the same group holds the Outer Sunset Farmers Market on that street every Sunday and, by its own count, reaches more than 200,000 people a year across its events. On site The market mixes vintage racks with local makers, live music from Bay Area artists and DJs, and food trucks; past editions have brought Bacon Bacon, Adam's Grub Truck, Shampa's Pies and Sunset Roasters. Each month takes a theme, and companion events run on site, from surf-focused celebrations and record swaps to DJ dance parties and tie-dye and zine-making workshops. The Artship, a shipping container turned all-ages art space, opens on the block during the market. Dogs on leashes are welcome, and Muni's 7, 29 and 48 lines serve the street. Audience The crowd is mostly neighbors: by Sunset Mercantile's count, 51% of its audience lives in the Sunset District and another 35% elsewhere in San Francisco. Families come for the rotating kids' activities, and the Recess Collective, a parent support group, has set up on the block. The organizers describe the shoppers as sustainability-minded, there for fashion, home decor, music and the neighborhood. Brand presence Sponsors buy in for all eight markets at Gold, Silver or Bronze. Gold takes a 10-by-10 space in a prominent spot at every market; the tiers add logos on posters and flyers distributed across San Francisco, in the e-newsletter and on paid local ads, dedicated social posts, flyers at the info table and shout-outs from the main stage. Themed options include a branded activity space, the food court or stage, a step and repeat photo spot and a special-event sponsorship.
