Even with its door wide open, Isaac Nichols’s Greenpoint studio is easy to miss. Walk past, look around, turn back, and there it is, tucked inside a cavernous, garage-like space that’s served as a creative home base for Nichols (who works under the name Group Partner) and a wide circle of artist friends for the past two years. The studio, unassuming from the outside, hums within: music plays; the stretch and tear of packing tape is constant. All around, laid out on makeshift surfaces and shelves, are Nichols’s signature pieces in varying stages of completion: ceramic pots molded to mimic breasts, each adorned in a hand-painted outfit, and his famous face pots, each with one of three appointed names: Adam, Rory, or Pat.
