This one is organized by the shop's circle rather than a third-party promoter, which tends to mean tighter curation — fewer mass-produced items filling table space. Two Marys' Mercantile leans toward handmade goods and curated vintage, so expect that to carry through to the vendor mix. If you've been to the smaller versions outside the shop, this is the same sensibility with more room to move.

Practical note: Alameda street parking is generally easier than SF, but the blocks immediately around popular Park Street spots fill fast on weekends. Come in from the Tube and park a few blocks off the main drag. Ferry is the low-stress option if the timing works.

If you've got two hours: walk the full vendor floor first without buying anything, then go back for what stuck with you. The early-pass stuff always looks different on a second look.
