There's more holiday not-exactly-shopping fun to be had in Brooklyn tonight at the New York Foundation for the Arts Swap Meet in DUMBO. Basically, you bring your old stuff and barter it around for new stuff, sort of like trading your strawberry pop-tarts for your best friend's oreos back in the elementary school cafeteria. Given the cool crowd NYFA attracts, there'll definitely be some fun stuff to be had.
It costs $5 to participate, but it all goes towards supporting NYFA Current, the Foundation's Art Magazine. Their current issue has a nice article on Brooklyn's own Laundromat Project if you need a reason to go.
