There are worlds in the sculptures of Jennifer Merchant. In her pieces, stars are born, planets are formed, and constellations become dust. In addition to drawing inspiration from the outer realms of the universe, Merchant also plays with the shape of crystals and geometric patterns. Fitting, considering the artist is also a jewelry designer, working with chunky pieces both colorful and celestial. Her sculptures and wearable items will be on display at Public Functionary this weekend only. Friday’s reception will include a live soundscape by Ian Lehman from 7 to 11 p.m., and a trunk show will pop up during gallery hours on Saturday.
