For nearly a decade, Etsy has been a virtual alternative to craft fairs, offering an online storefront for artists, designers, thrifters and crafters. But with the recent founding of regional meet-up groups like SoCal Etsy Guild, members are striving to take their businesses offline — at least for an afternoon — at in-person events. Enter Mom and Pop Up Shop. A one-day-only collaboration with permanent San Pedro marketplace Crafted, the pop-up shop boasts more than 50 artisan vendors inside the Port of Los Angeles' World War II–era warehouses (just down the street from the permanently anchored battleship USS Iowa) and an equal number of booths hawking jewelry, quilts, scarves, fine art and housewares on the breezy, waterside campus. The city offers free trolley service from the port to downtown San Pedro, but with grub from Vella Pizza and Gravy Train Poutinerie and a full lineup of DJs and activities, you may never want to leave the port. 110 E. 22nd St., San Pedro; Sat., April 27, 11 a.m.-6 p.m.; free. (310) 732-1270,

Sat., April 27, 11 a.m.-6 p.m., 2013
