The September Pottery Barn catalogue has propelled San Francisco designer Ken Fulk to the coffee tables of America. On the cover is the Fulk-designed caramel quilted leather sectional sofa, a wool giraffe-print rug and antiqued brass golden retriever bust. His coffee table, a cast aluminum model with a textured crocodile skin top, is edgier than the reclaimed wood and glass-topped iron tables the national chain is known for. And that’s exactly why Fulk, who hails from Harrisonburg, Va., was asked to design Pottery Barn’s first major designer collection, which launched in August. His 60 pieces of furniture, tableware and accessories, including swizzle sticks and hooks shaped like hooves, are priced at $6 to $10,000.
